34-438 50.8 x 50.8 mm Hoya G530 (VIS) Green Colored Glass Bandpass Filter 530nm

The 34-438 is a 50.8 x 50.8 mm Hoya G530 (VIS) Green Colored Glass Bandpass Filter, specifically designed for use in the visible light spectrum with a central wavelength of 530nm. This filter is sourced from the reputable optical components vendor, Edmund Optics.

The filter is a Color Glass type, characterized by its green-colored glass, which is engineered to allow light within a specific wavelength range to pass through while blocking other wavelengths. This makes it ideal for applications requiring narrow-band light transmission, such as fluorescence microscopy, spectroscopy, and other optical experiments.

The 34-438 filter has a rectangular base shape, with a width and height of 50.8mm each, providing a substantial surface area for light interaction. It has a thickness of 2.5mm, ensuring durability and rigidity. The filter features a Thin Lens shape, which is advantageous in applications where minimal optical path deviation is required.

The filter's physical data includes a Center Wavelength (CWL) of 530nm, indicating the wavelength at which the filter has its maximum transmission. This CWL is crucial in selecting the appropriate filter for specific applications.

The front and back surfaces of the filter are coated with EDM 34-435, a coating type that enhances the filter's performance and durability. This coating ensures optimal light transmission, reduces surface reflections, and protects the filter from environmental factors, thereby extending its lifespan.
