Spatial Filter Fixed Slits.

Gold plated one side, reverse side flat poly black up to 98% emissivity in visible and near infrared.

Standard Precision Air Slit.

High energy and high power copper slits are intended to be used in the optical transfer assembly of a system using a powerful laser as a source. For Q-Switching applications, consider a highly reflective slit disc surface and a very high melting temperature disc material. This material is able to withstand high energies from IR, Co2, ...

High energy and high power diamond slits are intended to be used in the optical transfer assembly of a system using a powerful laser as a source. For Q-Switching applications, consider a highly reflective slit disc surface and a very high melting temperature disc material. We will custom fabricate aperture mounts to comply with the ...

High energy and high power tungsten slits are intended to be used in the optical transfer assembly of a system using a powerful laser as a source. For Q-Switching applications, consider a highly reflective slit disc surface and a very high melting temperature disc material. Tungsten slits have X-rays, electron microscopes, and ...

High energy and high power molybdenum slits are intended to be used in the optical transfer assembly of a system using a powerful laser as a source. For Q-Switching applications, consider a highly reflective slit disc surface and a very high melting temperature disc material. We will custom fabricate aperture mounts to comply with ...

Named for Thomas Young’s classic proof of the wave theory of light in 1803. While Young’s original experiment used sunlight and calculated the average wavelength to be 550 nm, today using monochromatic and coherent light one can calculate wavelength with the following formula: In which, λ is the wavelength of the ...

The cross aperture may be used for measuring the modulation transfer function (MTF) of a detector array.

These blackened precision air slits may be used for optical applications requiring high resolution and low backscatter (stray reflected photons) for the input or output surfaces of the disc.

Our glass air slits are available only from the #1 coverslip material Thermanox. The optical properties closely resemble glass without some of the negative glass characteristics. The material is almost unbreakable, has no micro cracking and a refractive index of 1.64. The glass typically used has an index of 1.52. For further ...

Lenox Laser precision chrome-on-glass slits are used in a variety of optical instruments and systems, including spectrophotometers, line spread functions, masking and other applications

These elements may be used as entrance, exit or intermediate optical slits for spectrometers, photometers and monochromators, or for fourier/optical image analysis and other wavelength discrimination demonstrations.
