Precision Optics for High-Power Lasers

High power-handling capability, absence of retro-reflections and aberration correction for large core fibers truly differentiate these lenses from other fiber collimators.

The Model 02-M010 is a three-element, air-spaced anastigmat designed specifically for collimating the output of large diameter silica fibers used in high power medical and industrial applications. It is equally suitable for collimating the output of Large Mode Area (LMA) or Photonic Crystal (PC) fibers with smaller numerical apertures. The mechanical assembly allows a precise translation of the lens (without rotation) relative to the fiber face.

The unique design of the Model 02-M010 prevents retroflections near the fiber face or within the core material. All elements are fused silica (the exception being the 1800–2000 nm collimator optics that are Infrasil) with either V-type or broadband coatings, depending on the operating wavelength range. When used for imaging purposes, the three-element design ensures the output mode from the fiber is preserved, without distortion, even at high throughput powers.

Features

Fiber Connection Receptacles

The Model 02-M010 comes standard with SMA, or LD-80 (Richard Losch, Inc.)/D-80 (Mitsubishi) connector receptacles. Modifications to accept other types of fiber connectors can be made upon request.
