Note: Meaning of the code of HGL-AB/C:
H-- Hongyuan Company
G-- Ge material
L-- lens
A--the first digit represents the number of pieces composing the lens
B-- focal length
C-- F number (focal length/diameter, reversion is the relative aperture)
For example, HGL350-3/0.76 represents that the lens is composed of three piece, its focal length is 50mm, F number = 0.7
