Sharp Cut Filters ( L, Y, O, R )

	Sharp cut filters are filters that cut off the wavelength light shorter than a specific wavelength as much as possible, while transmitting the longer wavelength light as much as possible, within a wavelength range of 350 nm to 800 nm.

Transmittance

L37-L42

Use our transmittance simulation software for further information on transmittance.
