Three-scale imaging with an M72 lens
The magnification values listed for MVL-LF8040M-021V-M72 are 0.12x, 0.21x and 0.31x. The 80 mm focal length covers a 60 mm image circle through an M72 × P0.75 camera mount, and optical distortion is -0.11%. Manual focus and an F4 to F22 iris suit a fixed station in which geometry and illumination are established during commissioning.
The magnifications correspond to working distances of 750, 450 and 325 mm, each with ±9 mm tolerance. These pairings support line-scan or large-format inspection at three distinct object scales while preserving clearance for lighting and material handling. The lens is 45 mm in diameter, 108.28 to 116.28 mm long and 321.2 g, which helps define the camera carriage envelope.
MVL-LF6040M-013-M72 uses the same mount and 12 mm flange back length, but has a 60 mm focal length, 58 mm image circle and continuous 0.07x to 0.37x range. MVL-LF12040M-033V-M90 offers 0.31x to 0.38x at 480 to 558 mm with an 82 mm circle and M90 mount. Choose this 80 mm model for the 60 mm circle and its defined 750, 450 or 325 mm setups.

Selection and applications
Three-scale large-format inspection. Long-clearance line-scan imaging. Low-distortion registration.
Minimum kit: Attach the lens to an M72 × P0.75 camera interface and commission manual focus and iris at the 750, 450 or 325 mm distance assigned to the chosen scale.
Nearby in the range: MVL-LF6040M-013-M72 — Prefer it for an 8k, 7 µm line-scan camera and continuous 0.07x to 0.37x adjustment; MVL-LF12040M-033V-M90 — Prefer it for an M90 mount, 82 mm image circle and magnification up to 0.38x.

FAQ
Which distance should be used for each magnification setting?
Use 750 mm for 0.12x, 450 mm for 0.21x and 325 mm for 0.31x. Each working distance has a ±9 mm tolerance, so the camera bracket should permit positioning and focus adjustment around the selected nominal geometry.
What large-format mechanical interface does the lens require?
The camera-side mount is M72 × P0.75 and the flange back length is 12 mm. The optic covers a 60 mm image circle, making both the mount geometry and the sensor's required image coverage selection constraints.
Which controls remain manual after the lens is installed?
Focus and iris control are manual, with aperture adjustable from F4 to F22. The machine setup should therefore establish the selected magnification, working distance, focus and illumination before reference acquisition.
What is the thread at the front of the 80 mm optic?
The filter thread is M39 × 0.5. This is separate from the M72 × P0.75 camera mount, while the lens body itself is 45 mm in diameter and varies from 108.28 to 116.28 mm in length.
When should the 60 mm M72 lens be considered instead?
MVL-LF6040M-013-M72 is specified for 8k line-scan cameras with 7 µm pixels and covers 0.07x to 0.37x over 200 to 900 mm. Use this 80 mm lens when its three scale-distance pairs and 60 mm image circle match.
