Function of optical lens in optical system includes: focusing, collimating and imaging.

Lens type: Plano convex lens, plano concave lens, Double convex lens, double concave lens, meniscus lens, achromatic lens and so on.

Lens material: BK7, K9, quartz, germanium, silicon, zinc-selenide, magnesium fluoride and such high quality glass.

The lenses are always coated AR film to reduce reflection on the surface, so it can reduce the loss of energy and make the imaging more clear.

Size range: φ6-φ200mm

Size deviation: -0.02mm

Radius deviation: ≤0.001mm

Surface quality: 10/5, 20/10, 40/20, 60/40

Surface irregularity： 入/8~入/2

Clear apperture: ＞90%

Chamfering: ＜0.3mm x 45°

Coating: dielectric fim

Fibre laser collimating lens, fibre laser focusing lens

Focusing lens & Collimating lens are widely used in in laser cutting machine, laser detection, laser welding machine, optical imaging life science and other related fields. Focusing & collimating lenses focus the light source parallel to one point, so as to maximize the energy of the light source at this point, and make the object burn or sublimate rapidly for cutting and welding.Focusing lens substrate material is quartz and K9 crystal, in order to meet various requirements of customers, we have domestic materials (China) and imported materials (United States, Japan, Germany) focusing lens.

Most of the focusing lenses are plano-convex lenses and meniscus lenses.Since the meniscus lens has better focusing effect, if price is the same, we recommend the meniscus lens.For customers with special requirements, we can also provide plano-convex lens, double convex lens, double concave lens, plano-concave lens.

Lenses of DXS Optics has a high quality and stable film. The transmission rate can be higher than 99.95% after the lens is plated with double layer anti-reflection film, which enables the lens to achieve high energy, and because of the low absorption rate, the lens can be more resistant to wiping, not easy to take off the film.
