5.0mm Diameter, N-BK7 Half-Ball Lens

Product Details Fiber Coupling Half-Spheres Collimating Lenses TECHSPEC N-BK7 Half-Ball Lenses are ideal for applications such as fiber communication, endoscopy, microscopy, optical pick-up devices, and laser measurement systems. Half-ball (hemispherical) lenses can be interchanged with full ball lenses if the physical constraints of an application require a more compact design. These collimating lenses are uncoated, with a wavelength range of 350-2200nm. TECHSPEC N-BK7 Half-Ball Lenses are offered in diameters ranging from 0.50 to 10.00nm. Specifications General Type: Half-Ball Lens Physical & Mechanical Properties Diameter (mm): 5.00 Diameter Tolerance (μm): ±2.5 Thickness (mm): 2.50 Radius R (mm): 2.50 Radius Tolerance (μm): +0.0/-1.5 Optical Properties Substrate: Many glass manufacturers offer the same material characteristics under different trade names.
