66-040 12.5 mm Dia. Hoya O-54 Orange Longpass Color Glass Filter 540nm
The 66-040 is a 12.5 mm diameter color glass filter manufactured by Hoya, available through Edmund Optics. This filter is a Longpass type, designed to transmit light with wavelengths longer than 540nm while blocking shorter wavelengths.
The filter is made of a material identified as UVFS MAL-1965, and it features a Thin Lens shape. The geometry of the filter includes a diameter of 12.5mm and a thickness of 2.5mm. The cut-on wavelength is 540nm, and there is no specified cut-off wavelength.
The 66-040 filter is coated on both the front and back surfaces with EDM 66-040, a coating that enhances its performance and durability. The filter is currently in stock and can be purchased directly from the Edmund Optics website using the provided weblink.
This filter is ideal for applications that require the selective transmission of longer wavelengths, such as in fluorescence microscopy, astronomy, or machine vision systems. Its compact size and robust construction make it suitable for use in various settings, from laboratory research to industrial inspection.
