Model introduction

Product model

Lens (focal length, lens F-number) Gain mode Movement mode
LBL-HG341D 09010X: 9.0mm F1.0

13010X:13mm F1.0

25010X: 25mm F1.0

35010X: 35mm F 1.0

H: high quality

S: High image quality/wide range

NR: single imaging

WR: temperature measurement

Note 1: High image quality mode refers to the original high gain mode. In this state, the module response rate is higher and the imaging effect is good, but the temperature measurement range is narrow. The wide range mode refers to the original low gain mode. In this state, the module response rate is low. , the imaging effect is not good, but the temperature measurement range is wide.

Note 2: Lenses above 25mm are only used for imaging and do not have temperature measurement function.

Note 3: Supports lensless selection
