How to specify this lens

Send these four items and an engineer replies with datasheet and pricing within one business day.

Detector pitch and resolution

This catalog model is matched to 320×240 12 µm. Send the core part number so we confirm pitch, resolution, and window.

FOV or operating range

Target field of view or detection/identification range. If 6.8 mm is wide or tight, we shortlist 5 mm or 15 mm in the same detector class.

Sample qty and annual volume

Catalog thermal sampling from 50 pcs standard MOQ. Annual quantity sets production slot and price break.

Mount and documents

Sheet mount is M14×0.5. Ask for datasheet, mechanical drawing, or a custom thread in the first message.

Built and tested in our own optics factory

Every Lensmind thermal lens is machined, coated, cemented, and aligned in-house in Hangzhou. Core optical steps are not outsourced, so a drift found at final test can be traced the same day.

ISO 9001 process control on the production line

1 μm-class active alignment before the barrel is locked

Questions buyers ask about LMXHG-028

What is the LMXHG-028 thermal lens?

LMXHG-028 is a 6.8 mm F1.0 LMXHG thermal imaging lens matched to 320×240 12 µm uncooled detectors. Sheet mount is M14×0.5. Horizontal FOV is 31.6°; vertical FOV is 23.7°.

Which detector does it fit?

It is specified for 320×240 12 µm. Pixel pitch must match the detector pitch or MTF and coupling suffer. Send the core part number and we confirm this model or a nearby EFL in the same class.

What FOV should I plan for?

On the matched 320×240 12 µm detector, FOV is 31.6° horizontal and 23.7° vertical. These are the official sheet values, not series estimates.

What mount does the housing need?

Sheet mount is M14×0.5. If your housing uses a different thread, we quote a mount variant from the drawing.

Can you customize focal length, F/#, or mount?

Yes. 6.8 mm F1.0 M14×0.5 is the catalog starting point. Custom EFL, FOV, and mount variants are quoted from your detector drawing. Feasibility typically comes back with the first reply, within one business day.

Do you send a datasheet and mechanical drawing?

Yes. Open the inquiry form with the model, detector, and quantity. The reply includes the datasheet. Mechanical drawings go out at quotation stage.

What is the sampling MOQ?

Catalog thermal lenses support sampling from a 50 pcs standard MOQ. Sample fees are credited back when the volume order ships. Trade term is EXW with Guangzhou as the loading port.

Should I use 5 mm, 6.8 mm, or 15 mm?

LMXHG-027 is 5 mm, FOV H 43.6°, mount M16×0.5. LMXHG-028 (this page) is 6.8 mm, FOV H 31.6°, mount M14×0.5. LMXHG-029 is 15 mm, FOV H 14.6°, mount M14×0.5. Match FOV to range, or send both and we shortlist.
