Concave lens <focal length: -10 to -300>

By combining it with a convex lens, it is also possible to arrange the optical system!

A "concave lens" has a negative focal length and is used for image reduction and divergence applications. When combined with a convex lens, it is also possible to arrange the optical system to extend the working distance or expand the LD beam. The general usage method is the same as that of a plano-convex lens, using the concave side to face the parallel light beam. 【Specifications】 ■ Material: BK-7 ■ Refractive index: 1.51680/nd, 1.51872/ne ■ Design wavelength: 587.6nm (d line) ■ Chamfering (45°) with protective chamfer ・φ5: 0.1mm ・φ10 to φ100: 0.2mm *For more details, please download the PDF or feel free to contact us.

Synthetic quartz concave lens <focal length: -10 to -200>

It has a negative focal length and is used for image reduction and divergence applications! Custom orders for anti-reflective coatings and others are also possible.

The "synthetic quartz plano-concave lens" can be combined with a convex lens to extend the working distance or to expand the LD beam, allowing for adjustments to the optical system. The general usage method is the same as that of a plano-convex lens, where the parallel light beam is directed towards the concave side. Additionally, our synthetic quartz material (equivalent to ES) has a high transmittance in the ultraviolet wavelength range and excellent thermal expansion and thermal shock resistance. 【Specifications】 ■ Material: Synthetic molded S.F.S ■ Refractive index: 1.4585/nd, 1.4681/ne ■ Design wavelength: 587.6nm (d line) ■ Chamfer (45°) protective chamfer available ・φ3 to φ5: 0.1mm ・φ10 to φ100: 0.2mm *For more details, please download the PDF or feel free to contact us.

Biconcave lens <focal length: -5 to -100>

The material is Crown, BK-7! It has a negative focal length, which reduces the image size and diverges the light rays.

"Biconcave lenses" have a stronger power to diverge light beams compared to plano-concave lenses, making them suitable for use in lighting systems and finite imaging when combined with convex lenses. The main applications include telescopes, binoculars, cameras, and flashlights. They have a negative focal length, which allows them to reduce images and diverge light rays. Additionally, we accept custom orders for anti-reflective coatings and other specifications. 【Specifications】 ■ Material: Crown, BK-7 ■ Refractive Index: Crown (1.5230/nd, 1.5251/ne), BK-7 (1.51680/nd, 1.51872/ne) ■ Design Wavelength: 587.6nm (d line) ■ Chamfering (45°) with protective chamfering ・φ5: 0.1mm ・φ10 to φ100: 0.2mm *For more details, please download the PDF or feel free to contact us.
