850nm, 12.5 x 17.6mm High Performance Fluorescence Dichroic Filter

Product Details Improved Flatness, Transmitted Wavefront, and Surface Quality Ideal for Fluorescence Microscopy or High Magnification Imaging Applications Most Popular Cut-On Wavelengths of Fluorescence and Longpass Dichroic Filters Standard Fluorescence Dichroic Filters are also available Our TECHSPEC High Performance Fluorescence Dichroic Filters feature the same broad, flat transmission and reflection ranges as our popular TECHSPEC Fluorescence Dichroic Filters, but have improved physical parameters. Special attention to surface flatness, transmitted wavefront, and surface quality have resulted in our highest level of precision yet on a filter. These rectangular filters fit into most common Nikon, Zeiss, and Olympus fluorescence microscopes. High Performance Fluorescence Dichroic Filters are a perfect complement to our TECHSPEC Fluorescence Bandpass Filters. For specific wavelength or size requirements, numerous custom options are available. The TECHSPEC Dichroic Filters (sometimes referred to as dichroic plate beamsplitters or dichroic mirrors) feature broad, flat transmission and reflection ranges with an ultra-steep slope between them. These attributes make them ideal for fluorescence imaging or spectral sorting applications, including DNA sequencing and polymerase chain reaction (PCR) diagnostic instruments. Note: The filter should be oriented in such a way that the incoming light is incident on the surface that the chevron on the edge of the filter points towards (the dielectrically coated surface).
