How to recognize the Computar lens model
The first letter in a lens name indicates the sensor size. "T" stands for 1/3 inch CCD, "H" for 1/2 inch CCD, "M" for 2/3 inch CCD, and "V" for 1-inch CCD. If the lens has a CS-mount interface, the name will include "CS." Lenses without "CS" are C-mount lenses.
For example: H3616FICS-3 is a CS-mount lens, while H3616FI is a C-mount lens. The center of the four digits usually represents the focal length, with the first two digits indicating the focal length and the last two representing the F-number.
For instance: H3616FICS-3 means f=3.6mm and F1.6. If the second letter in an auto iris lens is "G," it indicates that the iris mechanism uses a galvanometer.
Auto iris lenses with a galvanometer (marked as "G") are divided into two types: FCS series (without amplifier, DC type) and AFCS series (with built-in amplifier, Video type). For example, TG2314FCS-3 is a DC type, while TG2314AFCS-3 is a Video type.
Lenses with an automatic aperture and built-in amplifier (Video type) end with "APC," which means the aperture mechanism is a circular servo type. For example, HAS3616APC is a circular servo type lens. The number at the end of the name indicates the version, such as H3616FICS-3 being the third generation.
Power zoom lenses have the zoom ratio indicated by the letters before "Z." For example, T6Z5710-CS means a 6x zoom (f=5.7mm to 34.2mm), and all lenses include a focusing mechanism.
Some lenses, like T2314FICS-3, have "FI" indicating an aperture adjustment mechanism, while T0412CS-3 has no "FI," meaning no aperture adjustment. However, this can't always be determined from the name alone. M1614WI includes an aperture adjustment mechanism.
Aspheric high-sensitivity auto iris lenses end with "-HSP." For example, HG3808FCS-HSP indicates the use of a high-sensitivity aspheric lens.
Manual zoom lenses typically have four digits in their name, or they may end with "-CS." Examples include T6Z5710-CS, H6Z0812, and M6Z1212.
Lenses with automatic iris and manual zoom, along with a galvanometer, use "AIDC" for DC type (no amplifier) and "AIVD" for Video type (with built-in amplifier). For example, T6Z5710AIDC-CS is DC type, while H6Z0812AIVD is Video type.
Power zoom lenses show features through the letters after the four-digit code. For example, T6Z5710AMSP-CS, H6Z0812PDC, etc. Here, "M" indicates motorized control for aperture, focus, and zoom. "MP" adds a preset function with a built-in voltmeter. "MS" includes a point filter, while "MSP" adds a preset function with a built-in voltmeter.
"AMS" refers to auto iris with an amplifier, controlled via DC motor. "AMSP" adds a preset function with a built-in voltmeter. "DC" is for auto iris without an amplifier. "PDC" is DC with a built-in voltmeter. "AMSR" adds over-bright remote control, and "AMSPR" adds a preset function with a voltmeter. "AMSC" includes an auto-off function, and "AMSPC" adds a preset function with a built-in voltmeter.
