- Telecentric lens with variable magni昀椀cation.
- 21MP resolution.
- Can be used as a macro lens with a variable magni昀椀cation between 0.5x and 1.0x.
4/3″ 21MP Macro Telecentric Lens Series
- Telecentric lens with a 昀椀xed magni昀椀cation.
- 21MP resolution.
- Can be used as a macro lens with a magni昀椀cation of 2.0x (昀椀xed).
2/3″ 5MP+ Telecentric Lens Series
- Intuitive lens selection based on pixel size.
- Optical magni昀椀cation range is fully adjustable.
- Optimized optical magni昀椀cation for 5MP sensor resolution.
- Low distortion design of 0.02% or less.
- Ensures consistent high contrast from center to edge for
optimal image clarity.
Telecentric optical systems are distinguished by their ability to
maintain consistent magni昀椀cation during focus adjustments,
enabling direct imaging of objects from the front (see Fig. 1).
This characteristic makes them particularly suitable for
high-precision dimensional measurements, especially when
exact positioning is required.
In these systems, the chief ray, which is the central light ray
from a point on the object entering the lens, runs parallel to
the optical axis. By setting the aperture at the image-side
focal point, the chief ray on the object side becomes parallel
to the optical axis. Consequently, when the object’s position
shifts along the optical axis, the image may blur, but the
magni昀椀cation remains unchanged.
