As shown in Figures 3 and 4, the first embodiment of the application optical module 100 is introduced.The optical module 100 is wrapped
The first optical module 10 and the second optical module 20 are included, first optical module 10 includes relatively-stationary photocell 11
And first lens 12, the center line of photocell exiting surface 111 is aligned with the first primary optical axis X1 of first lens 12；It is described
Second optical module 20 is included in the relatively-stationary lens 22 of light receiving element 21 and second, light receiving element receiving plane 211
Line is aligned with the second primary optical axis X2 of second lens 22；Wherein, when first optical module 10 and second optics
When component 20 is welded to each other together, the light that the photocell 11 is sent sequentially passes through first lens 12 and described
Second lens 22 and assemble to form the first luminous point 31 and the second luminous point 32 respectively, first luminous point 31 to second lens 22
Photocentre o2 first apart from a be more than second luminous point 32 to the photocentre o2 of second lens 22 second distance b.
In the present embodiment, photocell 11 can be laser, light receiving element can be optical fiber, but not as
Limit.When the first primary optical axis X1 is aligned with the second primary optical axis X2, the first luminous point 31 and the second luminous point 32 are respectively positioned on the first primary optical axis
On X1（Or the second primary optical axis X2）, because the second primary optical axis X2 is aligned with the center line of light receiving element receiving plane 211, now only
The distance of the second luminous point 32 and light receiving element receiving plane 211 need to be adjusted again, when the second luminous point 32 is received positioned at light receiving element
When on face 211, the coupling effect of light receiving element 21 reaches optimum value, and the second luminous point 32 now is Best Coupling luminous point
33.Here, the relativeness between the first primary optical axis X1 and the second primary optical axis X2 is larger on final exiting light beam intensity influence, when
When first primary optical axis X1 is aligned with the second primary optical axis X2, even if between having slightly between the second luminous point 32 and Best Coupling point 33
Away from also little on final exiting light beam intensity influence.
The optical module 100 of present embodiment employs two-lens system, and photocell 11 and the first lens 12 are advance
The first optical module 10 is fixed into, the lens 22 of light receiving element 21 and second are fixed into the second optical module 20 in advance, now, the
Error when one optical module 10 and the welding of the second optical module 20 is the welding error of whole optical module 100, and welding is missed
Difference can make the second luminous point 32 produce certain offset so that the second luminous point 32 deviates on light receiving element receiving plane 211 most
Good Coupling point 33.Because first is more than second distance b apart from a in present embodiment, the magnifying power M of the second lens 22 is less than 1（M=
b/a）, therefore, welding error can be less than by the offset of the second luminous point 32 produced after the second lens 22, compared to prior art
Middle deflection of optical point amount is at least welding 1 times of error, in the case where the acceptable deviation range of offset is certain, this embodiment party
Formula can greatly improve the acceptable welding error range of optical module 100, so as to reduce welding precision requirement.In addition, this reality
The welding manner for applying mode is to be initially formed the first optical module 10 and the second optical module 20, then carries out both welding, first
The optical module 20 of optical module 10 and second can independent assortment adaptation different application occasion.
Specifically, as shown in figure 4, the second optical module 20 is offset to dotted line position, it is assumed that welding error now is
Offset s, the bias s between one primary optical axis X1 and the second primary optical axis X2 cause second luminous point 32 to be connect with the light
A displacement s1 is produced between the Best Coupling luminous point 33 for receiving element 22, according to lens imaging principle, displacement s1 is offset s
With the magnifying power M of the second lens 22 product, i.e. s1=s*M, therefore, when the timings of displacement s1 mono-, magnifying power M is smaller, and welding is missed
The bias s that difference is produced is bigger, that is to say, that when the acceptable spot displacement amount s1 of light receiving element 22 error range one
Regularly, magnifying power M is smaller, and the acceptable welding error range in welding process is bigger, be subjected to welding error range with it is described
Magnifying power M is into inverse correlation.The magnifying power M of second lens 22 is designed to 0≤M by present embodiment<1, can effectively improve to connect
By welding error range, so as to reduce welding error precision requirement.It should be noted that acceptable welding error range here
It is primarily referred to as there is gap between the first primary optical axis X1 and the second primary optical axis X2, the gap is sent to final light receiving element 22
The influence of luminous intensity size is larger.

Into the first luminous point 31, second angle of divergence 42 is formed at the first luminous point 31, when the first luminous point 31 is saturating positioned at the first lens 12 and second
When between mirror 22, light dissipates to form the 3rd angle of divergence 43 again at the first luminous point 31, light shape after the second lens 22
Into the second luminous point 32, the 4th angle of divergence 44 is formed at the second luminous point 32.Here, because light receiving element 21 is in Best Coupling state
Under the angle of divergence be certain, i.e. the 4th angle of divergence 44 in Fig. 3 is certain, is connect in order to which light optimum state is coupled into light
Receive element 21, first angle of divergence 41 finally need to be collapsed into the 4th angle of divergence 44, in this way, then need control the first lens 12 and
The factors such as the spacing between the magnifying power of the second lens 22, the first lens 12, the second lens 22.Present embodiment is saturating using first
First angle of divergence 41 is first collapsed into second angle of divergence 42 by mirror 12, and second angle of divergence 42 is less than the 4th angle of divergence 44, in this way, matching somebody with somebody
The second lens 22 that magnifying power M is less than 1 are closed, the 4th required angle of divergence 44 is on the one hand can obtain, on the other hand can reduce weldering
Connect required precision.Here,, can be saturating by first because the dispersion angle of laser is larger when light emitting element 11 is laser
The magnifying power of mirror 12 is set greater than the magnifying power of the second lens 22, so as to which the first larger angle of divergence 41 is compressed into advance
Less second angle of divergence 42, is then amplified to the 4th angle of divergence 44 by the second lens 22 again.

First is more than the second luminous point 32a to the photocentre o2 of second lens 22 second distance d apart from c, present embodiment
Optical module 100a remains to realize the purpose of above-mentioned first embodiment.Compared to first embodiment, second embodiment by
In make use of virtual image luminous point, it may be such that the first lens 12 and second saturating 22 are arranged close to, in this way, greatly reducing whole optical mode
Block 100a size.
As shown in FIG. 6 and 7, it is the other embodiment of virtual image light spot position, those embodiments can also realize reduction
Welding precision requires and reduced the purpose of the size of whole optical module.The photocell exiting surface 111 and the light connect
Formation light transmission region between element receiving plane 211 is received, the virtual image luminous point is located at outside the light transmission region.Specifically
, as shown in fig. 6, first luminous point 31b of the light after the first lens 12 is virtual image luminous point, and the first luminous point 31b is located at the
Side of one lens 12 away from the second lens 22, the first of the first luminous point 31b to second lens 22 photocentre o2 is big apart from e
In the second luminous point 32b to the photocentre o2 of second lens 22 second distance f.As shown in fig. 7, light is saturating by first
The first luminous point after mirror 12 is virtual image luminous point, and the first luminous point is located at infinite point, the first luminous point to second lens 22
Photocentre o2 the first distance is more than the second luminous point 32c to the photocentre o2 of second lens 22 second distance g, now,
Magnifying power M=0 of second lens 22.
As shown in figure 8, the application also provides a kind of optical module preparation method, with reference to the explanation of above-mentioned optical module 100,
Including step：
The first optical module 10 is formed, first optical module 10 includes the lens 12 of photocell 11 and first, light transmitting
