Flaw detectors are nondestructive testing instruments that can detect or measure defects in raw materials or finished products.

Camera lenses and video lenses attach to video cameras for use in machine vision, quality monitoring, security, and remote monitoring for industrial and commercial operations.

Complementary metal oxide semiconductor (CMOS) cameras use image sensors that operate at lower voltages than charged coupled devices (CCDs), reducing power consumption for portable applications.

Optical apertures and slits control the diameter of beams from light sources.

Video cameras take continuous pictures and generate signals for display or recording.

Lens holders are used to stabilize and maintain the position of all the optical components of a lens assembly.

Beam expanders are optical lens assemblies that are used to increase the diameter of a laser beam or other light beam.
