Evaluate in the following manner optical path provided by the utility model can gradual change modification prism structures or prism battle array
The main performance of column.
(A) optical path modification effect
Using the maximum deflection angle γ of source of parallel light its reflected light after incidenta/γbSize assess optical path modification effect,
Bigger modification effect is more significant.The corresponding central angle θ of circular arc can also be useda/θbSize assess, as shown in table 1.In table 1
θa/θbRadius of curvature 13, symmetrical about circular arc at=5 °, 10 °, 20 °, 30 °, 45 °, 60 ° (0.5 ° of summary), about side circular arc
Outgoing optical focus 14, the distance 15 of focus to string, (radius of curvature R is with 100 as shown in Figure 10 for chord length 16 and its numerical relation
Unit indicates).
Using γa/γbOpinion rating: extremely weak (0 °, 1 °) < weak [1 °, 10 °) < it is weaker [10 °, 20 °) < it is moderate [20 °,
40 °) < relatively strong [40 °, 60 °) < strong [60 °, 90 °] < extremely strong (90 °, 120 °).
Accordingly use θa/θbOpinion rating: extremely weak (0 °, 0.5 °) < weak [0.5 °, 5 °) < it is weaker [5 °, 10 °) < it is moderate
[10 °, 20 °) < relatively strong [20 °, 30 °) < strong [30 °, 45 °] < extremely strong (45 °, 60 °).
Note: indicating when value range that round parentheses " (" or ") " indicate not include end value, square brackets " [" or "] " indicate include
End value
It is worth noting that, θa/θbIt is not the bigger the better, its applicability will be greatly reduced when bigger: being with left side parameter
Example, due to α3=α2+0.5θa, α1=α2-0.5θa, therefore work as α2(such as 60~75 °) or α when bigger2When smaller (such as 15~
30 °), if θaLarger (30~60 °), are more easy to cause α1< 0 ° or α3> 90 °, non-acute angle leads to not to form prism structures.
Therefore suggest θ hereina/θbRange is eventually held between weak~strong in modification effect and selects, i.e., 0.5~45 °, excellent
Select range weaker~suitable, i.e., 5~20 °, because inclined lower range universality is relatively more preferable, and limit more on the lower side is excellent in midrange
Selecting 10 ° is optimum value.
The opinion rating and relevant parameter of 1 optical path modification effect of table correspond to table
Note: being infinity at 0 °, i.e., do not cross, and 0~0.5 ° i.e. " close to infinity "." in structure " indicates focal length mistake
Closely, within 0.5 times of chord length.L=2R × cos (90- θa/ 2) D=0.5L × Sin (90- θ a)
(B) balance between the sensitivity and precision of optical treatment
Sensitivity and essence are evaluated using the deflection (same to mean direction angle) of prism structures bumps or side circular arc string
Degree, is considered as balance when sensitivity is identical with accuracy class, and 1~2 grade of rank difference when is considered as imbalance, and 3~4 grades of rank difference whens regard
To be extremely uneven, as shown in table 2.
When deflection becomes smaller, reflected light and incident light offset angular are smaller, i.e. deflection more hour sensitivity is lower, instead
It is also anti-, i.e., sensitivity is higher when deflection is higher.Therefore as shown in table 2, sensitivity evaluation grade is from low to high are as follows:
1 (0 °~20 °) < 2 (20 °~40 °) < 3 (40 °~50 °) < 4 (50 °~70 °) < 5 (70 °~90 °).
When deflection becomes smaller, unit projection area becomes larger, from it is incident (from distant place incidence can near normal it is incident) and instead
The amount of light penetrated is more, i.e., precision is higher when deflection is lower, vice versa, i.e., precision is lower when deflection is higher.Therefore
As shown in table 2, precision evaluation grade is from high to low are as follows:
5 (0 °~20 °) > 4 (20 °~40 °) > 3 (40 °~50 °) > 2 (50 °~70 °) > 1 (70 °~90 °).
The equilibrium relation evaluation table of 2 sensitivity of table and precision
(C) difficulty of processing
Carry out comprehensive assessment difficulty of processing from the acuity of structure sheaf, side sinking degree size and structure sheaf size.
Direction angle alpha of the acuity of structure sheaf by string2Or β2It influences, α2Or β2It is smaller more flat, α2Or β2It is more big more
Sharply.Flat structure is easily worked, it is not easy to be damaged；And sharp structure is exactly the opposite, hardly possible processing, is also easily damaged.
The side camber degree of structure sheaf is by θaOr θbIt influences, θaOr θbSmaller cambered surface is more straight, and bigger cambered surface is more curved.More
Straight cambered surface is more easily worked, macrostructure part more easy mold release, cutting, polishing, polishing, microstructure part be easier to filling, demoulding,
Calendering.And more curved cambered surface is then more difficult to process, macrostructure part is more difficult demoulding, cutting, polishing, polishing, and microstructure part is more difficult
Filling, demoulding, calendering.
The size of structure sheaf is influenced by height H, and H is bigger, and structure sheaf is bigger, vice versa.And size
All difficulty of processing can be simultaneously amplified or reduce, after being determined due to the processing method of macrostructure part and microstructure part,
Machining accuracy also determines that, under identical machining accuracy, size is bigger, and difficulty is lower, and the smaller difficulty of size is bigger.In general, working as H
Belong to 10-2When~1mm, belong to microcosmic processing scope, when H is closer to 10-2When mm, processing is more difficult to, and when H is closer to 1mm, is added
Work is simpler；In general, belonging to 1~10 in H2When mm, belong to macroscopic view processing scope, when H is closer to 1mm, processing is more difficult to, when
H is closer to 102When mm, process simpler；
