825nm 12.5mm Diameter, OD 2.0 Longpass Filter

Product Details Sharp Cut-On Wavelength High Rejection/Transmission Efficiency Precision Fused Silica Substrate Variety of OD 2.0 Longpass Filter Kits are Available TECHSPEC OD 2.0 Longpass Filters are designed to have a sharp transition from reflection to transmission, making them ideal for various applications. Available in a variety of cut-on wavelengths, these filters are designed for fluorescence and order sorting applications. These filters feature precision fused silica substrate and high rejection/transmission efficiency. TECHSPEC OD 2.0 Longpass Filters have a single-layer AR coating on the back surface that enhances the overall efficiency of each filter. Eliminate stray light by creating custom bandpass filters when combined with TECHSPEC OD 2.0 Shortpass Filters . A single layer AR coating on the back surface enhances the overall efficiency of each filter. Note : Due to supply chain issues, our kits may be delivered with an alternative packaging solution in place of a wooden box. For any questions, please contact [email protected] .
