Premium BSE Detector

4-quadrant detector for calibrated measurements and 3D analyses

Premium BSE detector is our highest performance Si-based detector for materials science, geology and industrial applications.

A four-quadrant sensor geometry is used, coupled with four independent in-situ preamplifiers, to give full flexibility for the traditional COMPO and TOPO modes, or the new calibrated 3D measurement mode with topographic reconstruction.

The motorised insertion/retraction mechanism allows for left/right and up/down directions, and has bellows for reliable vacuum.

An optional MICS-4 amplifier can be embedded into the detector, for a fully self-contained detector with quantitative amplification, independent brightness and contrast controls, and hardware signal mixing.

Port-mounted motorized BSE detector

Carefully selected segmented sensors are perfectly balanced with bespoke electronics and mechanics in a fully self-contained detector designed for ultimate performance and ease-of-use.

1. Premium Si sensor: Sensitive solid-state Silicon sensor with built-in 4x preamplifiers for ultimate speed and low acceleration voltage

2. XY alignment: High-precision lateral alignment with optional motorized repositioning

3. Built-in motorized insertion: Port-mounted and bellow-sealed with motorized insertion/retraction, and touch alarm

4. Standard interfaces: Control over USB 2.0 and analog video signals output on RJ45 connectors

5. Built-in amplifier and mixer: Two-stage amplification for each of the four channels, with independent and calibrated controls for brightness and contrast

Open control with full access to all detector parameters
