78MP Fixed Focal Length Lenses

Introduction

High resolution

Compatible with cameras which pixel ≥ 3.2μm and max. full frame (Ø44mm) sensor;

resolution up to 160lp/mm in full FOV.

Broad spectrum

The coating band is 400-1000nm, compatible with visible light and near-infrared band applications.

Floating focus structure design

The floating focus structure design is adopted to effectively ensure good optical performance under a wide working distance range^[1]

[1] Equipped with flange adjustment gaskets to maximize the optical performance of the lens used with the camera.

Specification Explanation
1.Working Distance (WD): The distance from the front of the lens to the object.
2.Aperture F/#: The actual working F/# of the telecentric lens.
3.Depth of Field: For a telecentric lens, the depth of field is estimated using the following formula:
F/#: The actual working F-number of the lens.
P: Sensor pixel size (5.5 μm for this calculation).
β: Lens magnification.
k: Dimensionless parameter based on the application; for measurement applications, k = 0.008 is used, but 0.015 can also be considered for calculation.
The depth of field at the nominal edge can still be used for measurement, but to achieve a clearer image, it is recommended to use half of the nominal depth of field.
5.Interchangeable Interface Accessories: Lenses marked with an asterisk (*) support the following optional interfaces:
OPT-RNxxxxxx-xxx-xxx287M42: Optional interfaces: M58, F-mount.
OPT-RNxxxxxx-xxx-xxx432M58: Optional interfaces: M42, M58, F-mount.
OPT-RNxxxxxx-xxx-xxx620M72: Optional interfaces: M42, M58, F-mount, M72.
OPT-RNxxxxxx-xxx-xxx820M90: Optional interfaces: M72, M90, M95.
