±60° Conoscopic Lens
Eckhardt Optics Stock Conoscope | Oct. 20th, 2020
The Cono60°XR is designed to test flat-panel displays (FPDs) or light sources with smaller diameters than 1.5mm. With a wide field of view (FOV) the Cono60°XR is able to capture the angular distribution of light from the source over 120° in a single frame from the camera. This allows very quick characterization of the light source being tested. The Cono60°XR is also designed with an extended wavelength range from 405nm – 780nm making it versatile for many different applications.
- 120° Field of View (±60° acceptance angle)
- 0.1° Angular Optical Resolution
- Designed for wide wavelength range from 405nm – 780nm
- 5mm Front Working Distance

60° HFOV Remote Sensing Lens
Sentera Sensors & Drones | Dec. 6th, 2022
This custom 60° HFOV lens was designed to replace an off-the-shelf solution. The custom lens was designed to improve resolution, reliability, and flight time by reducing weight. This lens is a good balance of wide field of view and resolution and delivers fast and accurate agricultural surveys compared to other products on the market.

Point Source Projector with Integrated Light Source
Eckhardt Optics Stock PHP | Dec. 6th, 2022
Point Source Projector with Integrated Light Source
The point source projector is capable of projecting an illuminated pinhole at virtual object distances from +100mm to -100mm (+10 diopters to -10 diopters). This allows the projector to simulate a point source (or a star) at almost any object distance, making it very useful for testing lens performance. When paired with Eckhardt Optics’ Point Source MTF software, this tool becomes incredibly powerful, allowing for the MTF testing of lenses at their designed object distance.
- Diffraction limited up to 5mm entrance pupil diameters
- External pupil for easy pupil position matching
- Virtual object distances from +100mm to -100mm
- Designed to be achromatic over the wavelength range: 430nm – 1000nm.
- Included light sources: white, red, green and blue (NIR LED units available upon request)
We use this projector to generate controlled point sources for measuring optical performance; learn more about our MTF testing methods by following the link below.
45mm F/3 Spectrometer Lens
Lightnovo | Jan 16th, 2025
The 45mm F/3 Spectrometer Lens (Lightnovo) provides diffraction limited performance across the visible and NIR. This makes it useful for working with different diffraction gratings for use in spectrometers varying in wavelength range and spectral resolution. The lens achieves >95% ensquared energy within a 5µm half-width making it very useful for high-resolution spectroscopy.
- Diffraction limited
- Wavelength range: 405nm – 1050nm
- 15mm Beam Diameter at Grating
- 18mm Front Working Distance
- Distortion < 1.0%

±80° Scatterometer (160° FOV Scatterometer)
Eckhardt Optics Stock Scatterometer | Nov. 3rd 2021
The ±80° Scatterometer is designed measure scattering off samples out to ±80° from the lens axis. This allows the scatterometer to fully characterize the sample in the time it takes the camera to take a single frame. This kind of acquisition speed is achieved by the conoscopic lens’ ability to convert all azimuths and field angles to positions on the image sensor. With better than 0.1° angular optical resolution, the ±80° Scatterometer outperforms goniometric measurement methods in resolution and speed.
- 160° Field of View (±80° acceptance angle)
- 0.088° Angular Optical Resolution
- Designed for wide wavelength range from 450nm – 850nm
- 1mm Front Working Distance
- Included Integrated BRDF and BTDF LED light sources: white, NIR, red, green and blue.

Ultra-Widefield Objective
Leeds Forensic Systems | November 21st 2019
The Ultra-Widefield Objective was designed as an attachment to a firearms comparison microscopes for Leeds. It adds the ability for firearms examiners to document large objects at low power on the same system that they document tool marks (on the same object) at high magnification. This gives the comparison microscope the ability to view objects up to 200mm in diameter at low magnification and objects as small as 0.155mm in diameter at high magnification on the same microscope.
- Attachment for Leeds Discovery and LCF3 Comparison Microscopes
- FOV up to 200mm in diameter
- Front working distance: 106.5mm
- Distortion < 7.5%
