46-434 50.8 x 50.8 mm SCHOTT BG38 (VIS) Blue-Green Colored Glass Bandpass Filter 470nm

The 46-434 is a 50.8 x 50.8 mm SCHOTT BG38 (VIS) Blue-Green Colored Glass Bandpass Filter, designed to pass light within the 470nm wavelength range. This filter is sourced from Edmund Optics, a leading vendor in the optical industry, and is available for purchase on their official website.

The filter is a Color Glass type, characterized by its ability to selectively transmit light of specific wavelengths while blocking others. This particular model is designed for use with visible light, hence the "VIS" in its name. The BG38 designation refers to its specific transmission characteristics, which are detailed in the SCHOTT catalog.

The filter has a rectangular base shape, making it suitable for use in a variety of optical systems. It is made from a material identified as "uvfs mal- 1965", and has a thickness of 3mm. The physical data of the filter includes a central wavelength (CWL) of 470nm, which is the wavelength at which the filter is designed to have its maximum transmittance.

The coating on both the front and back of the filter is "edm 46-433". This coating is likely designed to enhance the filter's performance, although the specifics of its effect on the filter's properties are not detailed in the item data.

The filter's geometry is that of a Thin Lens, suggesting that it may have some focusing or diverging properties. However, without additional information, it is not possible to definitively state the optical characteristics of the filter beyond its transmission properties.
