Introduction

Wide selection of lenses made from high quality UV FS, BK7 optical material. Round (dia from 12.5 to 76.5 mm, thickness from 2-6 mm) and rectangular (from 15x20 to 50,8x50x8 mm, thickness from 2-6 mm)) laser windows can be found in product catalogue, other custom sizes are available under request. Round (dia from 12.5 to 76.2; thickness form 3-15 mm) and rectangular (from 15x20 mm to 50.8x50.8 mm, thickness form 3-10 mm) precision laser windows, precision thin laser windows are available uncoated or coated with anti reflective coatings under customer’s request.

CNC Polished Precision Aspherical Lenses	UV FS Series Lens Kits	BK7 Series Lens Kit	UV FS Plano-Convex Lenses

Aspherical lenses are designed to reduce spherical aberration. We offer plano-convex aspherical lenses made of N-BK7, S-LAH64 or UVFS.	Lens kits contain 40 or 15 lenses made from UV grade fused silica. The kits are suitable for optics studies and research purposes where multiple focal length lenses may be required.	Lens kits contain 40 or 15 lenses made from BK7 optical glass. The kits are suitable for optics studies and research purposes where multiple focal length lenses may be required.	These simplest form lenses have flat surface on one side and spherical surface on the other. They are made of UV FS.

BK7 Plano-Convex Lenses	CaF2 Plano-Convex Lenses	UV FS Biconvex Lenses	BK7 Biconvex Lenses

These simplest form lenses have flat surface on one side and spherical surface on the other. They are made of BK7.	These simplest form lenses have flat surface on one side and spherical surface on the other. They are made of CaF2.	Biconvex lenses, made of UV FS, are all symmetrical. They are recommended for virtual imaging of real objects, and for positive conjugate ratios from 0.2 up to 5.	Biconvex lenses, made of BK7, are all symmetrical.

Plano-Concave Lenses	Plano-Convex Cylindrical Lenses	Plano-Concave Cylindrical Lenses

These lenses are thicker at the edge than in the centre and flat on one side. The plano-concave lenses are used to expand light beams or to increase focal lengths in optical systems.	These lenses are used to focus light to a thin line in laser scanners, spectroscopy, dye lasers, acousto-optics, optical processors and other similar applications.
