Newport 925B Compensated Attenuator
$350.00Newport 925B Compensated Attenuator.
The 925B Compensated Attenuator provides high resolution intensity control without introducing a gradient in the intensity distribution or a change in the beam propagation direction. The optical density can be varied from 0.16 to 3.0 through a top-mounted adjustment knob. It has a 1/2 inch (12.7 mm) diameter aperture. Attenuation is achieved by moving two matched BK 7 wedged filters in opposing directions. The filters have a linear-variable aluminum neutral density coating and a broadband antireflection coating. The slight wedge in the filters displaces any secondary reflections off-axis. The filters are matched for minimal beam deviation.

Newport / NRC F-l40 Laser Diode Multi Element
$175.00As per Newport Website:
The F-LA40B Laser Diode Multielement Objective Lens has been specially designed for collimating and focusing laser diodes as well as fiber coupling. This version has a 0.40 Numerical Aperture (NA) and a 6.24 mm focal length with 5 mm clear aperture. lenses. These lenses have all been corrected for the standard laser diode cover glass. Our multi-element lenses are precision optics with diffraction limited performance. They offer the best solution for more critical applications. The F-L40B has a triple V-coating for peak transmission at 800, 1300, and 1550 nm. These lenses offer an economical solution without sacrificing performance. These objectives are packaged in a microscope objective housing with standard RMS thread. They are compatible with our F-Series fiber coupling devices and ULTRAlign™ fiber positioners
This unit is on a mounting plate with base.

KLC K1148 Babinet Soleil Compensator
$1,600.00A Babinet Soleil Compensator ( BSC ) is placed between two crossed polarizers ( axes perpendicular to each other ) in such a way that the linear input polarization from the first polarizer is at 45 degrees to the fast axis of the compensator. Viewing through the second polarizer in a white light source, a black cross ( Null ) is observed at zero reading of the micrometer. This is zero retardation reading of the BSC. An unknown retardation to be measured is introduced between BSC and the polarizer. The BSC micrometer is turned until the black cross ( Null ) is observed again. The micrometer reading is an indirect measure of unknown retardation. A calibration chart is provided with each BSC which gives retardation in waves at a specific wavelength vs the micrometer reading.
