Holders
Beam Shaping Diffusers Holders

This holder is made for use on beam expanding or beam shaping.

Holders for Laser Beam Expanders

Holders for adjusting the angle of a laser beam expander. Compatible with various beam expanders with mounting threads on the input side of the expander. (BE, LBED)

BE-M

【It ended production.】

Laser Beam Expander [with Collimation Adjustment] (with holder)

Lens system that enlarges a small laser beam to a large collimated beam. Fine adjustment of collimation is possible with the collimation ring. Holders with fine tilt and rotation adjustment mechanisms enable setting of the orientation of output collimated beam to the same angle as incident beam.

Holders with integrated Laser Beam Expanders

Lens system that enlarges a small laser beam to a large collimated beam for simple experiments.
Holders with fine tilt and rotation adjustment mechanisms enable setting of the orientation of output collimated beam to the same angle as incident beam.

Adapters for Laser Beam Expanders

Adapters for mounting laser beam expanders to lens holders.
Compatible with all beam expanders of BE/LBED/LBE.

Spatial Filter Holders

Spatial filters are optical instruments for eliminating distorted laser wavefronts and noise to emit beams in clean spherical waves. Used in optical systems such as interferometers and holograms where wavefront quality is critical.

Precision Pinhole / Air Slits

Thin metal foil with a pinhole or slit of less than 400μm.
Used in spatial filters, laser diffraction experiments and microscopic magnification correction.

Two-axis Pinhole / Objective Holders

Holders for mounting a precision pinhole (PA) or precision air slit (FSL) and to adjust the position of the pinhole.

Standard Type

Holders for mounting a precision pinhole (PA) or precision air slit (FSL) and to adjust the position of the pinhole. Can be used to mount microscop...

Large Type

Holders allowing vertical and horizontal criss-cross fine motion within the plane perpendicular to the optical axis.

Pinhole

It is a Two-axis Holders of pinhole only. I will be used in an experiments such as diffraction.

Iris Diaphragm Holders

Iris diaphragm holders that can change the aperture size without changing the center of the aperture.
Uses include changing the depth of field by controlling the lens aperture in imaging systems and passing necessary laser beam while blocking optical feedback or stray light in laser experiments.

Iris Diaphragm

An iris diaphragm is used to adjust an aperture without changing the center of the aperture.
Primarily used in the limited spaces of optical instruments to set an aperture size.

Adjustable Slits

Adjustable slits have two razor sharp opposing blades that can be adjusted to vary the air gap between them.
Typical uses include spectrophotometers, Schlieren optical systems and diffraction experiments.
Especially useful in spectrometry and Schlieren optical systems where the slit can be varied tooptimize the light intensity and resolution of the instrument.

Standard Type

Typical uses include spectrophotometers, Schlieren optical systems and diffraction experiments.

Precision Type

I installed and used in the spectrometer.
