- N-BK7 optical glass
- ≤ λ/4 surface irregularity, 40-20 scratch-dig
- MgF2, multilayer broadband or laser line AR coatings available
- Custom diameters and focal lengths
Designed to meet the demanding requirements of laser electro-optic applications, N-BK7 plano-convex lenses are manufactured from fine annealed optical glass and are polished to tight tolerances using master test plates to ensure minimum wavefront distortion. T
N-BK7 is an excellent material for most visible and near infrared applications. It is the most common optical glass, and it provides great performance at a good value.
Standard or custom diameters from 6.35 mm to 76.2 mm allow for quick, easy mounting in many holders when building experiments or prototypes and complete upgradability from N-BK7 to fused silica singlets.
These singlet N-BK7 lenses are available either uncoated or multi-layer antireflection coated with a choice of broadband coatings or a laser line V-coating for 1064 nm.
