Frequently asked questions
What sensors does the CIL293 support?
The CIL293 supports 1/1.7″ sensors up to 16MP, including the IMX226 and AR2020, with 12-16MP resolution at 1.55μm pixel pitch.
What is the CIL293 image circle and field of view?
The CIL293 covers a 5.4mm image circle at a 190-degree field of view, which produces a circular fisheye on 1/1.7″ 4:3 sensors.
What does the 8G + 2MG optical construction mean on the CIL293?
8G + 2MG means eight conventional glass elements plus two molded glass aspheres. The aspheres make the stereographic correction and high edge MTF possible while keeping performance stable over temperature.
Is the CIL293 compatible with FLIR Blackfly S and Basler Dart cameras?
Yes. FLIR Blackfly S board and Basler Dart S-mount are mechanically compatible with the CIL293. Allied Vision Alvium and The Imaging Source M12 are also compatible.
Does the CIL293 ship same day from the US?
Yes. Orders placed before 12 PM PST ship same day from our San Diego warehouse. Contact us if you want to confirm current stock of the CIL293.
What is the chief ray angle (CRA) of the CIL293?
The CIL293 has an 11-degree chief ray angle, which matches back-illuminated sensors with microlens arrays tuned to that angular range.
