Gatan OnPoint BSE Detector

The OnPoint® detector is the standard for backscattered electron (BSE) detection that delivers unprecedented sensitivity and speed to better understand lightweight metals, polymers, plastics, and biological materials. Using a detector optimised for low kV, this system expands your ability to study low atomic number (Z) elements, uncoated biological samples, and large 3D datasets.

Features:

Resolves features distorted by charging or beam damage: Attains images at low kV to reduce charge build-up and to prevent damage to delicate samples
Captures large, 3D datasets quickly: Acquires large field of view images or 3D datasets up to six times faster
Differentiates low-Z elements: Delivers the highest signal-to-noise ratio (SNR) available to help differentiate between elements with a similar atomic number
Provides highest BSE collection efficiency: Produces higher SNR images because it captures electrons other detectors miss as well as minimises the noise in the detection system
Achieves most accurate quantification: Forms images with the widest dynamic range enabling the most accurate determination of elemental composition in alloys and compounds
