Plane Ruled Gratings

There are a wide range of ruled and blaze wavelength gratings, thy are widely used in biochemical instruments, spectral instruments, spectrophotometers, etc.

Optical Filter

CNI offers band-pass filter, high-pass filter, low-pass filter, dichroic filter, beam splitter, etc.


Raman Spectroscopy Filters

The filters are produced by the advance ion beam sputtering coating process of Veeco equipment.

Laser Goggles

Custom Design

Laser Safety Protection Board

An sufficient safety laser protection board adopts sandblasting surface treatment, has no selectivity to light source and is able to protect against laser and strong light effectively.

Laser Goggles

Beautiful shape, comfortable fit, high definition, extrusion deformation prevention material, able to protect human eyes from the laser radiation damage from 200nm to 1100nm.

Laser Power Meter

Two types: thermoelectric and photoelectric. The photoelectric type can be divided into high precision, desktop and handheld. Thermopile type is with wide measuring range.

Custom Design

CNI has the R&D ability to develop spectrum analysis system and components based on customer’s requirements.
