Frequently asked questions
What sensors does the CIL544 25mm C-mount lens support?
The CIL544 targets 1.1 inch sensors with 2.74μm pixel pitch at 20MP and above, including the GMAX0505, Lucid Vision TRI204S, and TRI245S.
Is the CIL544 aperture adjustable?
Yes. The CIL544 has a continuously adjustable iris from F/1.8 to fully closed. That gives you direct control over exposure and depth of field for your working distance and lighting.
What is the distortion on the CIL544 25mm C-mount lens?
The CIL544 measures -1% from rectilinear at minimum object distance. That level is low enough for dimensional measurement and metrology in many systems without software correction.
What is the working distance range for the CIL544?
The CIL544 focuses from 130mm to infinity. The design is optimized for both finite and infinite conjugate use, so close working distances stay sharp instead of rolling off at the edges.
Does the CIL544 25mm lens accept front filters?
Yes. The CIL544 has M30.5x0.5 front filter threads. That thread accepts common machine vision accessories such as ND filters, bandpass filters, and polarizers.
Does the CIL544 ship same day from the US?
Yes. Orders placed before 12 PM PST ship the same day from our San Diego warehouse. Contact engineering@commonlands.com if you need volume pricing on the CIL544.
