Steep cutoff, high blocking performance, high transmittance.
The ultra steep short pass filter is a high-performance hard-coated filter with a steep cutoff, high blocking performance, and transmittance. It has a sharp edge transition at a specific wavelength, allowing shorter wavelengths to pass through while reflecting longer wavelengths, enabling spectral separation.
Steep cutoff (laser wavelength <0.5%) • High transmittance • Wide blocking range
The ultra steep long pass filter is a high-performance hard-coated filter with high transmission rates and a wide blocking range. It features a steep edge transition (less than 0.5% of the laser wavelength) at a specific wavelength, allowing it to transmit longer wavelengths while reflecting shorter wavelengths, enabling spectral separation. In particular, in Raman spectroscopy, it is necessary to separate Rayleigh scattered light (laser wavelength) from weak Raman scattered light, and the steep edge transition and high blocking performance make it easy to measure Raman spectra.
Steep cutoff (approximately 1.25% of laser wavelength) - high blocking performance - high transmittance.
The standard long pass filter is a high-performance hard-coated filter with high blocking performance and high transmittance. It has a steep edge transition (approximately 1.25% of the laser wavelength) at a specific wavelength, allowing it to transmit longer wavelengths and reflect shorter wavelengths, enabling spectral separation. In particular, in Raman spectroscopy, it is necessary to separate Rayleigh scattered light (laser wavelength) from weak Raman scattered light, and the steep edge transition and high blocking performance make it easy to measure Raman spectra.
Narrow bandwidth, high blocking performance, high transmittance
This notch filter is a hard-coated filter with high blocking performance and a narrow bandwidth. It blocks only the narrow wavelength range before and after a specific wavelength, while allowing other wavelength ranges to pass through, enabling spectral separation. In Raman spectroscopy, it is possible to simultaneously detect Stokes Raman scattered light (longer wavelength than the laser) and anti-Stokes Raman scattered light (shorter wavelength than the laser).
High reflectivity and high transmittance dichroic mirror
The dichroic mirror is designed for an incident angle of 45°. It allows transmission on the longer wavelength side of a specific wavelength while reflecting the shorter wavelength side, enabling spectral separation.
Oil mist separator/blow-by filter
The introduction of oil mist separators not only greatly contributes to environmental protection but also provides various benefits such as improved engine reliability, cost reduction, and consideration for health and safety. UT99 is a Swiss company founded in 1947, leading the industry in specialized applications, including marine use.
