Improvement of the conventional design of kinematic mirror holders (MHG) . These holders are suitable for experiments which use a large number of simple mirror holders or for incorporation of mirror holder into production devices.

• These thinned holders can offer larger space for adjustment work compared to MHG.
• These holders hold a mirror at three points from the side in order to adjust the stress occurring when holding the mirror.
• Retaining rings do not cause constraints on the clear aperture so that a large clear aperture can be obtained with reflected light or transmitted light.

It is a product with lower quality than DLB series with low surface spherical achromatic lens.

Allowed to use optical system, which is not required high surface quality imaging lens such as the microscope lens and telescope lens.

• Specification except surface quality is almost the same as DLB series. Except when used in high-precision experiment using a laser, this lens is recommended.
• It is optimized so that focal length gap is small in the visible light range and the aberration is minimized.
• It is also corrected for astigmatism and comatic aberration of off-axis as well as aberration of axial object point.

For an illumination optical system and a simple experiment, it is not requested the low-scratch polishing for a laser. Reflectance and surface flatness is the same as aluminum mirrors (TFA) for a laser.

• The dirt on the surface of the mirror can be wiped because the scratch-resistant protection is coated on the aluminum coating.
• Reflectance of less variation can be obtained in a wide wavelength range from visible to near-infrared.

For the illumination optical system and a simple experiment, it is the glass substrate of which high surface quality used for the optical element is not required. Surface accuracy and parallelism (tolerance of wedged) is the same as optical flats for a laser.

• It is also available for manufacturing with a coating as requested to the plane substrate.
• In additional to the circle, square type, rectangular type of planar substrate, it is also available a wedge substrate and the parallel planar substreae which has high surface accuracy of both side.

It is the product that was reduced by one rank from the surface quality of Plano Concave Lens (SLB-N). It can be use in an optical system such as observation or lighting applications that high surface quality is not required.

• It has the same specification of Plano Concave Lens (SLB-N) except the surface quality. Unless a laser is used for high-precision experiments, it is recommended.
• There are two types of lens. One is a Plano Concave Lens with low spherical aberration and the other is a biconcave lens that is possible to shorten the focal length by a large refraction.
• In addition to uncoated products, there are three types of anti-reflection coating for visible, near-infrared, and infrared.

EVO Cam HALO digital microscope combines stunning 4K image quality with advanced, adaptive illumination to deliver unmatched
precision and versatility for inspection and measurement tasks.

F-Theta Lens converts rotational movement of a galvanometer mirror into a linear motion on a focal plane by utilizing distortion effects. Used for Laser Marking, Bar code Reader and Laser Micro machining industry and so on.

Premium hand-held infrared viewers that is extrememly helpful when trying to locate stray beams reflections from machine tooling, enclosures, laser rooms, or around curtain perimeters. Laser service personnel or lab students will make quick use of the product’s ability to safely align invisible near IR laser beams through optics and guide it safely to the designated work area.

ZAP-IT® Laser Alignment Paper is thermal-sensitive from ultraviolet to infrared; applications include laser beam alignment, beam profiling, and component positioning. Range of operation – pulse width: 1ns to 30ms, power level: 5 mJ/cm² to 20 J/cm² with patient applications.

The measurement of laser power is quick and simple with the Power Wizard power meter.

This hand-held meter is a low cost, light-weight alternative to bulky, 2-piece thermopile power meters and probes, or traditional ‘meat thermometer’ probes.

This probe is ideally suited for industrial, scientific and medical applications.

Use it when setting up your system and as a service tool to insure maximum performance of your laser system.

Model PW-250 measures output power from ultraviolet to the far infrared (1 – 250W).

Automatic data hold and auto ranging make the Power Wizard easy to use.

Simply insert the sensor into the laser beam and hold it in place for a few seconds. The easy-to-read LCD screen will then display an accurate reading of average laser power.

To take another reading, simply push the reset button and the meter is ready to go again.

High stability kinematic mirror holder with Sigma Koki’s unique locking mechanism (Nomi Lock™). Nomi Lock™ is a new type of locking mechanism that enables adjustment of the torque of adjustment screws. It is best suited for usage in interferometers and laser processing devices where beam displacement after adjustment is a problem.

• With their simple structure, excellent rigidity and stability, kinematic mirrors holders are used in interferometer and laser resonators.
• There are two types of mirror holders, a high stabilty model (MHG-HS) and a production model (MHG-MP).
• The high stability model (MHG-HS) is fitted with large knobs, and allows adjustment of the point of support in addition to the two points of action as well as displacement of mirrors in the vertical direction.
• When Nomi Lock™ is used in interferometer, the displacement in the optical axis will be within a single fringe.
• Mirrors are fixed at three points on the lateral side so that the stress caused by fixing mirrors can be adjusted.
• Providing large clear aperture of reflected light or transmitted light since retaining rings and the like do not impose any constraints on aperture.
