Spatial Filters and Accessories		Features
	Three-Axis Spatial Filters	• Precise, long-travel 3-axis micrometer adjustments • Accommodates virtually any microscope objective • Unobstructed view of pinhole aids adjustment • Easy pinhole removal and replacement
	Compact Five-Axis Spatial Filters	• Compact, stable, 5-axis design • New high-resolution, 100 TPI XYθXθY adjustment screws, 80 TPI Z-adjustment • New zero-freeplay XY mechanism provides precise, smooth motion • New independent, non-influencing locks on each axis lock the mechanism to maintain stable alignment • Integral iris diaphragm aids in beam alignment
	Mounted and Unmounted Pinholes for Spatial Filters	• Mounted pinholes for SB18YZBM positioner • Unmounted replacement pinholes
	High-Energy Pinhole Apertures	• High laser damage threshold • Ultra-thin substrate minimizes laser power loss • Smooth, round apertures • Available mounted or unmounted
Beam Shapers and Collimators		Features
	Laser Collimator	• 10x beam expansion • Diffraction limited performance • Low wavefront distortion • AR coated Galilean optical system • Optimized for the visible spectrum
	Refractive Beam Shapers	• Converts Gaussian beam input to flat top output • High energy conversion - accepts 99.7% of input energy • High profile uniformity - flat top has 10% RMS power variation (15% RMS for GBS-UV-H) • Collimated output beam allows use of conventional optics after beam shaping • Provides performance over large wavelength ranges
Optical Systems and Sets		Features
	Faraday Optical Isolator, Free-Space	• Broad free space optical isolator offering • High Verdet constant • Low absorption coefficients • High damage thresholds • Tunability over a broad spectral range
	High-Energy Variable Attenuators	• Up to 40 dB dynamic range • Broadband transmission • High damage threshold • Negligible beam deviation • Replaceable actuator on 3 and 5 mm aperture versions
	Compensated Attenuators	• Uniform attenuation across aperture • Compensated dual-wedge design • Wide dynamic range • High resolution • No multiple reflection fringes
	OptiSet™ Optics Sets	• Comprehensive collection of mirrors, lenses, filters, beamsplitters, and objectives • Clearly identified part numbers marked on each optic • Conveniently organized in a hardwood case
