Optical Lenses / Visible & VIS–NIR

Objectives & eyepieces

Visible and VIS–NIR optics shown with matched engineering parameters.

Objectives and eyepieces are separated because they solve different system tasks. Every product image below is linked to its own parameter record; expand a card to inspect the full reference specification.

Visible & VIS–NIR imaging

Low-light and wide-angle objective lenses

Reference configurations cover fast-aperture low-light imaging, extended VIS–NIR response and ultra-wide scene coverage. Detector fit must be reconfirmed for every project.
