Before this configuration is released
What to confirm with us
Send these five inputs and the quotation can be prepared against your system rather than against a catalogue headline.
01Detector type, resolution and pixel pitch, including the cold-shield or cold-stop interface
02Required horizontal field of view, or the focal-length range and zoom ratio
03F-number, aperture envelope and the mounting interface on the host system
04Focus mechanism travel, control interface and the near-focus distance
05Operating temperature range, sealing target and the inspection documents required at release
