Electron Spin Resonance (ESR)
MiniScope MS 5000
Extend your lab’s capabilities with the benchtop EPR/ESR spectrometers. The versatile MS-5000 and MS-5000X are research grade instruments with sensitivity and reliability for demanding applications.
Compact Single-Channel Analyzers (SCA)
bPAD SCA
bPAD is a compact microcontroller-based Intelligent Single Channel Analyzer. The device contains a Preamplifier-Amplifier-Discriminator with TTL digital output.
bPAD+ SCA
The bPAD+ is an enhanced version of the bPAD  SCA This device adds an extra analog pulse output, which can be connected to an external MCA for monitoring purposes.
bPAD+ VR
The bPAD+ VR is an enhanced version of the bPAD+ SCA. This model's analog output can be setup to use the pulse signal or a variable voltage level relative to the discriminated count rate.
bMCA USB
The first of BrightSpec's Compact Digital Multi-Channel Analyzer series, this MCA is designed to be used with scintillation detectors, this MCA is built into the tube socket, taking very little space.
bMCA Box
A special version of the bMCA (USB or Ethernet), where the tube socket has been replaced by a single SHV connector. It works for a wide range of detectors supplied with a single connector carrying the signal and high voltage supply.
bMCA Ethernet
This is the Ethernet version of the bMCA. Using an Ethernet connection instead of USB allows installing the device in remote places. Data transfer rates are also tremendously improved. 
Compact Digital Multi-Channel Analyzers (MCA)
Topaz-Pico
Topaz-Pico is a compact, stand-alone digital Multi-Channel Analyzer (MCA), which is able to perform Pulse Height Analysis (PHA) of the signal produced by a standard scintillation detector such as NaI(Tl), LaBr3 (Ce), LaCl3(Ce), etc.

Topaz X
Topaz-X is a compact, stand-alone digital Multi-Channel Analyzer (MCA), which is able to perform Pulse Height Analysis (PHA) of the signal produced by high resolution, Peltier-cooled semiconductor detectors, such as Silicon Drift Detectors (SDD) and Si-PIN diodes.
Topaz-Pico BNC
​The Topaz-Pico BNC is a special version of the compact Topaz-Pico Multi-Channel Analyzer, where the Lemo connectors have been replaced by standard BNC connectors.
Topaz HR
Introduced March 2018, Topaz-HR is a compact stand-alone MCA for high-resolution detectors such as Hyper Pure Germanium Detectors (HP-Ge). 
Portable Spectrofluorimeter
LEDµSF
 A portable spectrofluorimeter for non-invasive analysis of cultural heritage artworks using LED sources. The LEDµSF is essential to answer critical questions during the scientific analysis of materials in artwork.
