Edmund Optics® (EO), the premier provider of optical components, introduces three new TECHSPEC® Hard Coated Filters: High Performance OD 4 Shortpass Filters, High Performance OD 4 Longpass Filters and Imaging Filters. These new lines join existing Hard Coated OD 4 Bandpass Filters with series at 10nm (213 models), 25nm (108 models) and 50nm (147 models). All of these filters have the advantage of fabrication using “hard coated” plasma deposition technology, which ensures high performance and allows for exceptional durability. They provide high transmission of designated wavelengths and deep blocking of unwanted wavelengths, featuring maximum blocking within a few nanometers of the laser wavelength, to isolate narrow spectral regions in a wide variety of applications.
TECHSPEC High Performance OD 4 Shortpass and Longpass Filters provide cut-off slope of <1%
TECHSPEC High Performance OD 4 Shortpass Filters and Longpass Filters both feature a cut-off slope of <1% with a rejection of OD≥4.0 and 91% transmission in the pass band. Shortpass filters are available in 103 models, in wavelengths from 400nm to 1300nm in diameters of 12.5mm, 25mm and 50mm. The VIS Shortpass Filter Kit includes seven filters between 400-700nm and can be integrated into our filter wheels. Longpass filters are offered in 99 models, in wavelengths from 400nm to 1300nm in diameters of 12.5mm, 25mm and 50mm, with new 325nm, 350nm, and 375nm options available in September. Shortpass and Longpass filters may be combined to create a customized precision bandpass filter to eliminate stray light.
TECHSPEC Imaging Filters ideal for machine vision
TECHSPEC Imaging Filters are designed to meet demanding machine vision and imaging applications. Optimized for use with popular LEDs, the imaging filters pass or block specific UV, Visible, or IR wavelengths to provide very wide angles of incidence. Extremely high and flat transmission profiles provide even illumination; the filters improve image contrast and isolate spectral regions and colors. TECHSPEC Imaging Filters are available in 90 models with multiple mounting sizes and threads for easy system compatibility. All TECHSPEC Imaging, Shortpass, and Longpass Filters are in-stock and available for immediate delivery for fast turnaround and excellent value.
