400nm CWL, >OD5, 20nm FWHM Bandpass Filter, 25mm Dia.

Product Details Suitable for Single-Point Fluorescence Detection and Flow Cytometry Applications 52 Distinct Design Wavelengths Covering the NUV – NIR Spectrum >OD5 Average Blocking from 330 – 900nm Mounted for Easy Handling and System Integration Hard Coated OD5 Bandpass Filters are available in 52 distinct passbands with design wavelengths from 340 to 895nm in step increments of 10-15nm in the NUV, VIS, and NIR. These cost-efficient hard-coated filters feature high transmission (>90%) with full-width half maximum (FWHM) of 20nm, or 30nm in the NIR, for essential optical performance. Hard Coated OD5 Bandpass Filters feature high average blocking >OD5 outside the passband from 330 – 900nm, making them suited for flow cytometry and single-point fluorescence detection, such as photometry and point-scanning. All filters are mounted in 25mm diameter black anodized aluminum rings to facilitate handling and system integration. Specifications General Type: Bandpass Filter Typical Applications: Scattered light and point detection (Flow Cytometry), not suitable for imaging, immunophenotyping Note: Arrow on ring indicates preferred direction of propagation of light.
