Description
Aperture Insert Set 1 2 15 30 Degree Photometer Spectrometer Optical Accessory
Set of 4 interchangeable aperture inserts for photometers, spectrophotometers, and spectrometers. These inserts restrict and define the light cone angle during optical measurements, allowing operators to select measurement geometry based on sample and application requirements.
Specifications & What's Included
- 4 black anodized aluminum aperture plates: 1°, 2°, 15°, 30° angles
- Thumbscrew retention with bracket mount system
- Compatible with standard photometer and spectrometer optical benches
- Material: Black anodized aluminum
Applications
Aperture inserts are fundamental accessories in spectrophotometry and photometric measurement systems. They control the solid angle of light acceptance, enabling precise colorimetry, reflectance measurement, and optical density testing across various sample geometries. These inserts are commonly used in laboratory spectrometers and industrial color measurement instruments where geometry-dependent measurements are required. Narrow angles (1°–2°) measure small or localized areas; wider angles (15°–30°) accommodate larger samples or diffuse measurement conditions.
This set of four aperture inserts — marked 1°, 2°, 15°, and 30° — has been inspected and appears to be in good used condition. The units were pulled from a working optical measurement environment. The black anodized plate bodies show light surface patina and minor wear consistent with lab use, and the thumbscrew hardware is intact on all four pieces. The aperture openings appear clean and undamaged. Please view our photo set and contact us if you have any questions.
