Optical performance and model-specific limits
Use the numerical model limits together with MTF, field-curvature, distortion and transmission plots to evaluate image quality across the required field.
The model table contains this family’s available technical record
Focal length, aperture, working distance, distortion, illumination, filter and mount data are listed by model. A separate optical-performance or mechanical plot is not available for this family.
Match the compact lens to sensor, field and closest focus
Start with the sensor and required field of view, then compare optical and mechanical constraints within one complete model row.

Confirm compact C-mount clearance and focus access
Use one row’s focal length, sensor size, angle of view and minimum object distance. Obtain the exact outline for the selected model before freezing a constrained machine envelope.
Sensor
Do not exceed the selected row’s 1/1.8- or 2/3-inch format.
Field
Confirm the listed angle on the actual camera.
Focus
Reserve at least the row-specific minimum object distance.
Envelope
Confirm barrel clearance, iris/focus access and C-mount engagement.
