Longpass filter that cut the short wavelength and let the long wavelength transmit.

The OSE-VND are reflcetive ND filters. The reflectivit and the transmittance vary by rotation.

Filters are designed to divide sharply the wavelength color by transmitting the short wavelength and cutting off the long wavelength.

Divides sharply the color of wavelength by reflecting the short wavelength and transmitting the long wavelength.

This is a vapor-deposited aluminum flat mirror in which the substrate has been polished to a high degree of accuracy and is designed for high reflectivity at any angle of incidence.

Silver (Ag) coated mirrors have a high reflectance over a wide range from visible to infrared wavelengths.

These simple plano-convex lenses have a flat surface on one side and a spherical surface on the other side. They are also very close to the shape that minimizes spherical aberration for infinite conjugate applications

These reflective microscope objectives are optimized for chromatic aberration over a bandwidth of 350 nm to 7 µm.

These objectives are educational microscope objectives.

Precise bandpass filters for use in microscopy, Raman spectroscopy, imaging and much more.
