Rectangular Optical Filters Datasheets

435.8nm CWL, 40.0nm Bandwidth, 120.0 x 20.0mm dia. Optical Bandpass Filter -- 435.8 / 40.0 - 48749
from Andover Corporation

Andover maintains a stock of high-quality surplus optical bandpass filters. These are primarily overruns of custom production lots, and exhibit the same high level of quality as all of our other products. Consequently, this can be a very economical alternative to purchasing a custom bandpass filter. [See More]

Linear Variable Fused Silica Neutral-Density Filter -- LNDQ-2-100.0M
from CVI Laser Optics

Linear variable neutral-density filters provide variable attenuation as the filter is translated. These filters can be used with white light as well as with low power lasers. A large finite aperture can be attenuated by translating two filters in opposite directions. Low density values are more... [See More]
