542AF135 28 mm Dia. Surface Coating; Bandpass Filter Surface Coating

The 542AF135 is a high-quality bandpass filter, designed and manufactured by Omega Optical, a leading vendor in the optical industry. This filter, with a catalog number 542AF135, is specifically designed for applications that require precise wavelength selection and blocking of unwanted spectral ranges.

The filter features a circular geometry with a diameter of 28 mm and a thickness of 2.5 mm, making it suitable for a wide range of optical systems. It is made from UVFS MAL-1965, a material known for its excellent optical properties and durability.

The 542AF135 has a cut-on wavelength of 475 nm and a cut-off wavelength of 610 nm, with a central wavelength (CWL) of 542.5 nm. This means it allows light in the green spectrum to pass through while blocking light in the blue and red spectrums. This makes it ideal for applications such as fluorescence microscopy, spectroscopy, and other applications where specific wavelength selection is crucial.

The filter is coated on both sides with Omega's proprietary coatings, OME 542AF135, which enhances its performance and durability. The coating provides improved transmission, lower autofluorescence, and better environmental stability. The filter's shape is thin lens, which is beneficial for applications where space is a constraint.
