Lens 20mm focus 38mm. Thermal Imager ht-a2. Really increased detail. But there are problems with fastening specifically to this thermal imager. This lens should stand closely to the lens of the thermal imager, which prevents the use of any nozzles or additional holders for this lens.

Good quality, everything works, ordered more. Delivery to Nizhny Novgorod is fast enough. The seller is very grateful.
