I.Application
Infrared camera lens with spectral range 0.8 ~ 2.4 u m.
II. Requirements
Applicable wavelength: 3 ~ 5 μ m
EFL: 1.0 in (25 mm)
Lens quantity: no more than three pieces
Lens maximum diameter: less than 15 mm
Lens facial type: all spherical
Lens material: optical glass
Lens gross weight: less than 10 g
Detector size: 1 in (16 mm)
Maximum aperture: 2
Rear intercept: more than 16 mm
Resolution: more than 20 lp/mm@0.5; 24 lp/mm@0.4; 36 lp/mm@0.3
III. Features
This lens belong to middle infrared lens which needs expensive but rare material and low transmittance, so lens thickness shall be as thin as possible. Due to long wavelength, and requirements on resolution is low. This design type is similar to Cooke triplet.
