and photomasks features an 8-in. stage, tilting viewing head, and fingertip operation capability. The microscope's optical system produces high-resolution and high-contrast images in all illumination modes. Darkfield imaging and TV imaging for digital recording are standard. Additional features include

Shedding light on vision systems
, if a specific FOV is needed, a fixed-lens design may be less expensive than a zoom lens that includes the right field of view but with a lot of unused adjustability. Or if the illumination is constant, the iris can be fixed at one setting. If several lens elements are called for, the costs of a custom
