87-277 25 mm Dia. Multi-Edge Fluorescence Dichroic Filter 436/514/604nm

The 87-277 is a 25 mm diameter Multi-Edge Fluorescence Dichroic Filter, specifically designed for applications involving multiple wavelengths. This filter, sourced from Edmund Optics, is a high-quality, circular component with a thickness of 1.05 mm, making it suitable for a wide range of optical systems.

The filter is designed to cut on at 436 nm, effectively blocking or reflecting light below this wavelength. It does not have a specified cut-off wavelength, indicating that it allows the transmission of wavelengths above 436 nm. This makes it ideal for applications that require the separation of specific wavelengths, such as fluorescence microscopy or multi-spectral imaging.

The 87-277 features a multi-edge coating on both the front and back surfaces, identified as 'edm 87-277'. This coating enhances its performance, particularly in terms of wavelength selectivity and durability. The filter's geometry is that of a thin lens, suggesting that it may also have some light-focusing capabilities.

The filter's physical data, including its diameter and thickness, are precisely controlled during manufacturing to ensure consistent performance. The 25 mm diameter provides a good balance between light-gathering capability and compactness, making it suitable for many optical systems.
