Hard coat filter for fluorescence measurement
This bandpass filter is a hard-coated filter with high transmission rate and high blocking performance. It allows transmission only in the wavelength bands around a specific wavelength, blocking other wavelength ranges.
Japan Vacuum Optics, meeting various optical needs.
It is a filter that utilizes the interference phenomenon of reflected light occurring at the interface of a thin film to selectively transmit light of specific wavelengths.
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.
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.
Japan Vacuum Optics, meeting various optical needs.
It is a filter that transmits infrared light by forming a multilayer film on optical substrates such as quartz, sapphire, Si, and Ge, utilizing the effect of the interference film.
