RET638lp C 25 mm Dia. Longpass Filter by Chroma
The RET638lp C is a longpass filter with a 25 mm diameter, manufactured by Chroma. This filter is designed with a circular base shape and a thin lens form factor, making it an ideal choice for applications requiring minimal thickness and weight. The filter features a chromium (chr) coating on both the front and back surfaces, enhancing its optical performance.
The RET638lp C filter has a catalog number of RET638lp and is available directly from Chroma's website, where you can find additional information and specifications. According to the vendor, the filter is currently in stock, ensuring quick delivery and minimal lead times.
This longpass filter has a cut-on wavelength of 638 nm, allowing it to transmit light at this wavelength and above. The cut-off wavelength is 0 nm, which means it will block all wavelengths shorter than 638 nm. This specific wavelength selection makes the RET638lp C suitable for various applications, such as fluorescence microscopy, spectroscopy, and other optical systems where specific wavelength discrimination is required.
The RET638lp C filter is built using UVTF Mal-1965 material, ensuring high-quality performance and durability. Its physical dimensions consist of a 25 mm diameter and a 1 mm thickness, making it compatible with most optical systems and components.
