48-636 25.4 mm Dia. Hoya B-440 (UV-VIS) Blue-Green Colored Glass Bandpass Filter 440nm

The 48-636 25.4 mm Dia. Hoya B-440 (UV-VIS) Blue-Green Colored Glass Bandpass Filter is a specialized optical component designed for applications in the ultraviolet and visible light spectrum. Sourced from the renowned optical vendor Edmund Optics, this filter is a part of their extensive catalog of optical elements.

This filter is characterized by its circular shape with a diameter of 25.4 mm and a thickness of 2.5 mm. It is made from a unique material, identified as "uvfs mal- 1965", which is specifically designed to handle UV and visible light. The filter is designed to pass light at a central wavelength of 440nm, making it ideal for applications that require the selective transmission of blue-green light.

The physical data of the filter includes a center wavelength (CWL) of 440nm, which is the wavelength at which the filter has its maximum transmittance. The filter's coating, applied on both the front and back surfaces, is identified as "edm 48-632". This coating likely serves to enhance the filter's performance and durability.

The filter's geometry is that of a thin lens, suggesting that it may have some light-bending properties in addition to its filtering capabilities. This could make it suitable for use in optical systems where both filtering and lens functionality are required.

According to the provided information, this filter is currently in stock, and its vendor-provided web link is valid. This indicates that users can readily purchase and incorporate this filter into their optical systems.
