Hera: cost effective spectrometer for display measurements
The Hera 01 with lens is the ideal spectrometer for display measurements where ease of use, stability, performance and price are essential. A perfect solution for hassle free integration in production processes.
Highlights
• Spectral range 380-780nm
• Spectral output or colour values output are both possible
• Auto-range function
• Luminance range of 0.05 – 6000 cd/m²
• Excellent linearity over entire dynamic range
• Dark current compensated, virtually zero over entire integration range
• Holographic grating for low stray light
• USBTMC compliant, SCPI command set, high speed device
• Numerous interfaces, ideal for system integration
• All spectral calculations are done inside
• Several lens system options
• Robust housing
Speed & ease of use
Admesy strongly believes in developing and manufacturing devices where ease of use and speed are key factors. In order to achieve these aspects, Admesy considers the following aspects of spectrometers to be taken care of.
• Wavelength calibration
• Dark current
• Linearity
• Absolute calibration
Calculations and compensations are done in a staggering 14ms. All this is possible due to the high speed processor inside the Hera combined with algorithms developed for this specific device. In production processes, no external calculation power is needed from computers. Data can be used directly in production settings without any delay of processing data afterwards. This saves time and processing power of the operating system of a production line. Additional feature is the Hera’s auto-range function: the most ideal integration time is chosen automatically. Manually, the integration time can be changed.

Hera lens specifications
The Hera series is available with several lens systems, available as fixed optics and optics with fibres. For fibre connections, Admesy uses M8 connectors. This connector has been developed to connect the optical fibre in a consistent way to ensure the best possible repeatability.1 Models 1, 2 and 3 are collimating lens systems and can be used closely to the display
Speed & performance, Hera 01 20mm
1 Speed and repeatability are directly related to each other; a lower repeatability can increase speed and vice versa.
2 Measurements are real life taken measurement and can vary slightly from device to device.
