Beam Expanders
Edmund Optics Inc.Request Info
TECHSPEC DA (divergent adjustable) fixed broadband beam expanders from Edmund Optics Inc. are optimized at a wide range of wavelengths for maximum flexibility, making them ideal for use with demanding tunable laser sources.
They feature a 1940-nm design wavelength to complement lasers with wavelengths from 1900 to 2100 nm, which are ideal for highly precise applications, including medical surgery and plastic processing, because of their unique absorption characteristics and ability to create very small and precise cuts in both biological tissue and plastics with minimal localized heating.
TECHSPEC DA broadband beam expanders are available in high- and low-power models with 2× and 3× magnifications. Low-power models feature standard 7980 fused silica; high-power models feature 7979 fused-silica substrates to ensure minimal IR absorption within the substrate. A threaded barrel divergence adjustment compensates for input beam divergence. The beam expanders are coated for 1940- to 2100-nm performance, easily integrated into prototype and advanced applications, and maintain the highest quality across the adjustment range.
