Product description

This longpass filter is designed to enhance spectroscopy applications by allowing wavelengths longer than 633 nm to pass through while effectively blocking shorter wavelengths. With a high transmittance of 90% and excellent blocking depth of OD>6 at 532 nm, it is ideal for use in fluorescence microscopy and other optical systems that require precision wavelength separation. The filter is made from durable fused silica with a hard coating, ensuring environmental durability and reliability in various conditions.

Key Features

  • Transmittance of 90% ensures high light throughput for optimal performance.
  • Longpass design effectively blocks wavelengths below 633 nm, enhancing signal quality.
  • OD>6 blocking at 532 nm minimizes unwanted interference from shorter wavelengths.
  • Custom sizes available (D8 to D50) to fit specific application requirements.
  • Low minimum order quantity of 1 piece allows for prototyping and testing.
