basic information
Continuous variable density filters are ideal for precise light attenuation and adjustment in spectrophotometers, monochromators, and lasers. The optical density changes linearly with respect to the long axis of the filter. By using two continuous variable density filters as a pair, the transmittance of light beams up to 25.4mm in diameter can be adjusted very smoothly. For the product lineup, specifications, and sales prices of standard products, please refer to the relevant product page on the official website of Edmund Optics Japan (accessible from the product homepage link above). *You can download the catalog featuring this product from the link below on the Edmund Optics Japan website.
