The 380DIB25 is a 25 mm diameter Standard Interference Bandpass Filter, specifically designed to pass light in the 380nm wavelength range. This filter is sourced from Knight Optical, a reputable vendor known for their high-quality optical elements.
The filter is made from UVFS MAL-1965, a material specifically chosen for its optical properties in the ultraviolet spectrum. It has a base shape of a circle, a common choice for its uniformity and ease of integration into various optical systems.
The 380DIB25 has a thickness of 6.1mm, providing sufficient structural integrity while minimizing unwanted optical effects. The cut-on wavelength is 375nm, and the cut-off wavelength is 385nm, ensuring a tight bandpass around the desired 380nm wavelength. The central wavelength (CWL) is also 380nm, indicating the peak transmission wavelength.
Both the front and back surfaces of the filter are coated with KNI 380DIB, a proprietary coating developed by Knight Optical. This coating enhances the filter's performance and durability, making it suitable for a wide range of applications.
The filter's shape is described as a Thin Lens, suggesting it may have some light-bending properties, although this is not explicitly stated in the provided data.
The filter is currently in stock and available for purchase through the vendor's website, as indicated by the 'Valid - in stock' status in the item data.
