Spectroradiometers, Display Spectrometers, Lighting Spectrometers, OEM Spectrometers
Explanation:
Spectroradiometers are used to separate, quantify, and analyze the spectral characteristics of a light source, providing industry-specific insights based on a light’s wavelength intensities or frequency. They use a grating to split light into wavelengths of different bandwidths and funnel that light through the spectrometer using integrated concave mirrors. These high optical throughput components ensure a maximum amount of sampled light reaches a high sensitivity sensor for analysis. High-end spectrometers may even include a series of optical filters or a filter wheel to improve the equipment’s wavelength range, enabling a higher dynamic range of light over the entire wavelength range of the device.
Display technology has grown exponentially in recent years, with emerging technologies such as organic light emitting diodes (OLEDs) challenging the conventional liquid crystal display (LCD) market. Digital devices such as smartphones, tablets, and televisions are subsequently built with more vibrant and dynamic displays than ever before. Spectrometers have been instrumental in supporting this period of growth and innovation, finding use in process and quality control applications.
The Rhea series advanced spectrometer is routinely used during the production of LCD and OLED based display technologies as a master instrument to adjust the display’s optical characteristics and maintain exceeding levels of batch-to-batch consistency combined with several colourimeters like the Hyperion or MSE series.
Light emitting diodes (LEDs) and solid-state lighting (SSL) have effectively supplanted halogen and fluorescent bulbs due to their superior levels of efficiency and tuneability. It is increasingly possible to fine-tune the optical characteristics of LEDs and SSL to display distinct aesthetic characteristics, such as dimming or changing colours. This is all enabled through improved interconnectivity between devices, greater digital driver quality, and fundamentally better light measurement technology.
Spectrometers are crucial for enabling the growth of LEDs and SSL, by maintaining exceptional optical characteristics or products throughout production, thus enabling new functionalities. The Rhea series spectrometer is capable of measuring for multiple lighting parameters, including spectral power distribution, colour, and colour rendering properties. These parameters can, for example, be used to match white points of different LED luminaries between product batches
Original equipment manufacturers (OEM) commonly rely on light measurement specialists to provide suitable spectrometers for integration with their own innovative machinery. The potential applications for OEM integration of spectrometers are significant, which is why high-end spectrometry equipment is increasingly equipped for flexibility and configurational variation. This enables individual customers to configure the spectrometer to their unique specifications, gaining the full potential of the measuring component and improving the functionalities of their own products.
The Rhea series is built to be fully integrational with OEM, with a broad wavelength range of 200 – 1100 nm depending upon the product application.
