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.
