The precision slits or air slits can be used as entrance, exit or intermediate slits for spectrometers, photometers and monochromators etc.

The high precision slits also can be used in confocal microscopy, hyperspectral imaging instruments, Lidar or for fourier/optical image analysis various educational optical experiments and other wavelength discrimination demonstrations.

What’s more,  slits can be used in metal 3D printing optical systems, medical devices, such as confocal fundus imaging systems etc.

With cutting edge technology and professionals, we have gained rich experiences for the slits customization, and also we have standard slits at stock for fast delivery.
