Abstract
The utility model discloses a high-precision single-side/double-side platform optical lens which comprises a lens body, wherein a single-side or double-side positioning platform is arranged in a non-active region of the lens body. The high-precision single-side/double-side platform optical lens is reasonable in structure; the pitch of an optical system of a photoelectron instrument is reduced; the diameter of a light path is reduced; the luminous flux of the instrument is increased; the quality of the optical system is more effectively ensured; the positioning of the product in the instrument is stable; the whole weight of the instrument is reduced; the quality of the instrument is increased; and the applicability of the instrument is increased.
Description
Technical field
The utility model relates to a kind of optical lens.
Background technology
Existing optical lens is the concavo-convex eyeglass of common arc, and the location steadiness is undesirable, influences serviceability.
Summary of the invention
It is a kind of rational in infrastructure that the purpose of the utility model is to provide, the high precision single face of favorable working performance/two-sided platform optical lens.
The technical solution of the utility model is:
A kind of high precision single face/two-sided platform optical lens comprises phacoid, it is characterized in that: the non-active region in phacoid is provided with the single or double locating platform.
Said locating platform is individual layer, bilayer or three layers.
The utility model is rational in infrastructure, has reduced the pitch of photoelectron instrumental optics system; Dwindled the light path diameter, increased the instrument luminous flux, the optical system quality has obtained higher assurance; Product is firm in the location of instrument neutralization; Alleviate instrument complete machine weight, improved the instrument quality, promoted the applicability of instrument.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Fig. 1 is the structural representation of an embodiment of the utility model.
Fig. 2 ~ Figure 13 is the multi-form product synoptic diagram of the utility model.
Embodiment
A kind of high precision single face/two-sided platform optical lens comprises phacoid 1, two-sided locating platform 2,3 is set in the non-active region of phacoid, or is the single face locating platform.
Said locating platform is individual layer (shown in Figure 2), double-deck (shown in Figure 5) or three layers (shown in Figure 7) etc.
When the utility model is made; Concave-concave or biconvex optical mirror slip after machining action face are ground to stepped appearance or circular arc platform on request in non-operation area; Platform is divided into individual layer, bilayer, three layers and does not wait as requested, and platform has two-sided parallel and double side arc shaped etc.Add man-hour; The technical requirement of processing platform as required; Make the high precision plated diamond grinding wheel of opposite platform shape, utilize the centring edging machine do not damage under the workplace prerequisite guaranteeing, just can disposablely grind the brand-new optical lens that size and dimension on request has platform.The platform sand face that grinds does not evenly have bright spot and edge damage takes place; The platform diameter error can be controlled in the positive and negative 0.005mm; The depth error of platform is controlled in the 0.005mm, and frosting smooth finish reaches 0.025. workplace smooth finish and is up to state standards more than the optical element smooth finish grade II grade standard.
Claims (2)
1. high precision single face/two-sided platform optical lens comprises phacoid, and it is characterized in that: the non-active region in phacoid is provided with the single or double locating platform.
2. high precision single face according to claim 1/two-sided platform optical lens is characterized in that: said locating platform is individual layer, bilayer or three layers.
