1200nm 25mm Diameter, OD 2.0 Shortpass Filter

Product Details Sharp Cut-Off Wavelength High Transmission / Rejection Efficiency Precision Fused Silica Substrate Our TECHSPEC OD 2.0 Shortpass Filters are designed to have a very sharp transition from transmission to reflection, making them extremely useful in several applications. With an average transmission of 85% and an average blocking optical density of 2.0, excellent contrast can be achieved in machine vision and gauging applications. Available in a variety of cut-off wavelengths, they are ideal for fluorescence applications, separating spectral orders, and creating custom, efficient bandpass filters when combined with TECHSPEC OD 2.0 Longpass Filters . TECHSPEC OD 2.0 Shortpass Filters have a single layer of AR coating on the back surface that enhances the overall efficiency of each filter. These filters are designed with a precision fused silica substrate. Note: Due to supply chain issues, our kits may be delivered with an alternative packaging solution in place of a wooden box.
