52-543 25 mm Dia. Yellow Dichroic Filter; t=2mm 520nm

The 52-543 is a 25 mm diameter dichroic filter, specifically designed for optical applications that require precise wavelength control. This filter, sourced from Edmund Optics, is made from borofloat33, a high-quality glass material known for its excellent optical properties and durability.

The filter's primary function is to reflect or transmit light within a specific wavelength range while blocking other wavelengths. In this case, the 52-543 filter is designed to cut on at 520nm, allowing light at this wavelength and above to pass through, while cutting off at 0nm, effectively blocking all wavelengths below this point. This makes it ideal for applications that require the isolation or enhancement of yellow light.

The filter's geometry is another notable feature. It has a thickness of 2mm, which is thin enough to minimize optical distortions and light loss due to reflection, yet sturdy enough for practical use. The circular shape, a common form factor in optical components, ensures easy integration into various optical systems.

The coating on both the front and back surfaces of the filter is edm 52-542, a proprietary coating developed by Edmund Optics. This coating enhances the filter's performance by improving its reflectivity and transmissivity within the desired wavelength range.
