Full parameter record
25 mm Lightweight Low-Light Objective – published specifications
Every value below is the reference record for this configuration. Values marked as a reference, a target or a minimum are confirmed against the detector datasheet and the approved drawing before a quotation is issued.
| Parameter | Published value |
|---|---|
| Focal length | 25 mm |
| F/# | ≤1.23 |
| Image-plane compatibility | Detector or image-plane interface to be confirmed against the selected optical drawing. |
| Field of view | ≥40° for 17.5 mm image format |
| Distortion | Sign, magnitude and acceptance limit at 20° half field to be confirmed against the supplier drawing. |
| Weight | ≤41.2 g |
| Sealing reference | Waterproof to 20 m for ≥2 h |
Reference policy: the signed quotation, approved drawing, sample and inspection plan define the delivered performance, coating, sealing, MOQ and lead time. Values published here are engineering references for screening, not a guaranteed specification.
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.
01Image format and pixel pitch of the sensor the objective will serve
02Required field of view, F-number and the distortion limit at the field edge
03Low-light level, spectral range and the coating reference for the working band
04Mount thread, back focal distance, mass and the mechanical envelope
05Sealing and shock requirements, plus the sample and inspection documents required
