Various lens holders are available, ranging from the holder to hold a circular lens and mirror in place which facilitates centering to an easy-to-use type and another holder with which a cylindrical lens can be held in place.
(including C-357, HL-C30, HL-R30, C-28, etc.)

We provide a wide variety of mirror holder products, including the one that holds a circular mirror in place, another one that secures a rectangular mirror in position after it is glued and so on.The tilting screw for fine adjustment is enlarged as much as possible to improve the operability.Included among them are the holder of upper-area control type which provides easy control even for optical system arrangement, the holder of gimbal structure type where the center of fine angle adjustment matches the reflection center of mirror, and others.
(MHA-50, MHA-S50, MHF-50, MHS-60B, MHJ-54, etc.)

These holders are used to hold polarization elements in place, such as polarization plate, wave plate (wave retarder) and Glan-Thompson prism.They are also provided with a rotation mechanism of element which is required for operation of polarization plane.
(POH-30, POH-50, etc.)

The spatial filter consists of a lens and pin hole, which is used to remove interference fringes generated from debris or scratch of the lens through arrangement of the pin hole in a light-focus position of the lens and to create a diffuse light which is free from noise and finely formed.This filter is termed a spatial filter because it is a device used for spatial filtering.

As a lens which is applied to the spatial filter, an objective lens for microscope is used.This is because a short focal length (several millimeters) and spherical aberration are calibrated, and others.A pin hole's diameter is calculated from a wavelength of the light source and a focal length of the objective lens, both of which are to be used. And, a pin hole with a proper diameter (several μ millimeters to 50 μ millimeters) should be used.

The diameter of a pin hole to be used is determined by the following expression:

They are the products designed to extract a beam of light having a required diameter only via a circular aperture and aperture diaphragm blades.There is also a slit-like aperture diaphragm which is not circular in shape.
(AD-8, C-56, etc.)

Our product range includes the camera holders with which commercially available camera lenses, CCD and digital cameras equipped with a JIS-approved attachment member for tripod can be fixed in position.
(HC-41, HC-61, HC-T2, C-54-N and so on)

These holders are designed to hold an optical fiber in place and to bob such fiber in the vertical plane of optical axis.
[C-53-(2) and C-53-(3)]

They are the products with which screen, light shielding plate, thin samples, etc. are held in place.
(FH-30, FH-60, FH-160)

They are designed to measure the power (light intensity) of a laser beam.The circular-form and rectangular-form types are available for the sensor and light receiving part, which are selectable for the intended use.
(8230E, 82311B, 82321B, etc.)

The available pieces of equipment are protective glasses and light shielding plates for exclusive use which are mainly used for protecting eyes against damage caused by a laser beam during work operation using such laser beam.Other types of protectors are also available for each wavelength, complete absorption, work tasks, etc.In addition, we also offer warning labels which can serve as warning signs for a working area/environment using a laser beam.
