The 66-081 is a 50 mm diameter color glass filter from Edmund Optics, specifically designed for longpass applications with a cut-on wavelength of 455nm. This filter is part of the SCHOTT GG455 series, known for their high-quality optical glass and precise coatings.
The filter is circular in shape and has a thickness of 3mm, making it suitable for a wide range of optical systems. It features a thin lens shape, which helps minimize optical aberrations and ensures high image quality. The filter's geometry is designed to provide excellent light transmission and blocking capabilities, with a cut-on wavelength of 455nm and a cut off of 0nm.
The 66-081 is coated with EDM 54-650 on both the front and back surfaces. This coating enhances the filter's performance by reducing surface reflections and increasing transmission efficiency. The coating also provides excellent environmental stability, ensuring the filter maintains its performance over time.
This filter is currently in stock and available for purchase through the Edmund Optics website. It is a versatile and reliable option for applications that require longpass filtration, such as fluorescence microscopy, spectroscopy, and optical sorting.
