48-637 25.4 mm Dia. SCHOTT BG39 (VIS) Blue-Green Colored Glass Bandpass Filter 507nm

The 48-637 is a 25.4 mm diameter bandpass filter from Edmund Optics, designed for use in the visible light spectrum. This filter features a specialized blue-green color, achieved through the use of SCHOTT BG39 glass, which provides excellent transmission characteristics at the specified central wavelength of 507nm.

The filter is characterized by its circular shape and thin lens design, which contribute to its compact form factor and ease of integration into various optical systems. The geometry of the filter includes a diameter of 25.4mm and a thickness of 3mm, providing a robust and stable platform for optical applications.

The coating of the filter is another notable feature. Both the front and back surfaces of the filter are coated with EDM 48-637, a proprietary coating developed by Edmund Optics. This coating enhances the filter's performance by reducing surface reflections and improving transmission efficiency.

The physical data of the filter includes a center wavelength (CWL) of 507nm, which is the wavelength at which the filter provides the highest transmission. This makes the 48-637 an ideal choice for applications that require precise filtering in the blue-green region of the visible light spectrum.
