FLM/FLMHP
Zoom

This mirror is designed to provide low wavelength dispersion suitable for use with ultra-short pulse lasers with 100 femtosecond or less.

◦We have designed a special thin film coating that optimizes wavelength dispersion, range and the strength of lasers.
◦It has the effect of suppressing the spread of the pulse width produced by a plurality of reflecting mirrors.
◦There are three types available, FLM1 standard, FLM2 wide wavelength band, and FLMHP for high power femtosecond laser*.
◦These mirrors are designed and produced for usage within the microscopy with femtosecond laser and optical systems with femtosecond time-resolved spectroscopy.

▶These low dispersion wavelength mirrors are available in physical dimensions other than those found in the catalog, please contact our Sales Division for Custom products.
▶We can also provide high power negative dispersion mirror.
▶Also available are our surface flatness guarantee (HTFM) mirrors with accuracy guarantee after surface coating.
W3002

Attention

▶When used in angles other than 45 degrees (AOI), we would not be able to guarantee the wavelength dispersion.
