ATAKT V-7HS OEM Spectroradiometer

The V-7HS uses a high-speed spectral sensor and optimised optics to drastically cut measurement times. It can capture a low-luminance reading (around 0.5 cd/m²) in about 250 ms. In contrast, many conventional spectroradiometers might take up to 10–14 seconds for a similar low-light measurement. This means the V-7HS delivers results much more quickly, which is invaluable for high-volume testing or real-time adjustments on a production line.

"OEM spectroradiometer" means the device is designed as a component for Original Equipment Manufacturers to integrate into their own systems or equipment. Unlike a handheld or standalone lab instrument, the V-7HS comes in a module form factor that can be mounted inside testing machines, integrated into automated quality control setups, or built into custom measurement rigs. It’s essentially the core spectroradiometer technology packaged for integration rather than for direct end-user operation, giving engineers flexibility to incorporate it into various platforms.

The integrated CCD targeting camera allows you to see exactly what area the spectroradiometer is measuring. When setting up a test, you can use the live camera view (typically through the control software) to align the instrument with the precise spot on a display or light source. This removes any guesswork or need for peering through a scope or eyepiece. The camera not only ensures accurate aim but can also capture an image of the test spot, which can be saved alongside measurement data for documentation or analysis.

As a full spectroradiometer, the V-7HS provides the spectral power distribution of the light it measures (usually across the visible wavelengths), from which it can derive detailed photometric and colorimetric data. In practice, you get precise luminance readings (cd/m²), chromaticity coordinates (CIE x,y or u’v’), correlated colour temperature (if applicable), and other metrics like CRI or spectral peak wavelength if needed. Essentially, it gives both the raw spectral data and the key calculated values for colour and brightness, which is essential for thorough display and lighting analysis.

The ATAKT V-7HS offers a standard 50 mm fixed-focus lens which works well for general-purpose measurements at a set distance, as well as an optional 75 mm zoom lens that can be adjusted for different target sizes or distances. The choice depends on your test setup: for instance, if you need to measure small areas or need flexibility in working distance, the 75 mm zoom might be preferable. The lenses are interchangeable; you can swap lenses to suit different test scenarios. Additionally, if those options don’t meet a specific need, the manufacturer can provide custom lens solutions to accommodate unique field-of-view or focal distance requirements.

The V-7HS is built with integration in mind. It has two built-in ¼″-20 UNC threaded holes on its body, allowing you to bolt or secure it to frames, brackets, or motion systems. This standard thread size is common for optical and photographic mounting hardware. In a production environment, for example, you might fix the spectroradiometer onto a gantry or an arm that positions it in front of the device under test. Its robust housing ensures it can be mounted securely without losing alignment, even if there’s vibration or movement around.

Yes, it’s designed for use in real-world conditions, including factory floors. If ambient light is present, it can influence measurements, especially of low-light outputs, but the V-7HS has an available solution: an optional ambient light遮光罩 (hood) accessory. This luminance hood attaches to the device and masks out external light, effectively shielding the measurement spot from stray illumination. By using this accessory, you ensure that the spectroradiometer is only capturing the light emitted by your test subject, making measurements accurate even under typical room lighting.

The ATAKT V-7HS is particularly beneficial in industries and applications where fast and precise light measurement is critical. This includes display manufacturing and calibration (for smartphones, TVs, automotive dashboards, etc.), where it can quickly verify brightness and colour of screens or backlights. It’s also useful in LED and lighting product testing, ensuring LEDs meet their luminance and colour specs. Because of its speed and sensitivity, it’s ideal for automated optical inspection systems in production lines — for instance, checking every unit on an assembly line for correct illumination or colour uniformity. Research labs and quality assurance departments dealing with low-light measurements or seeking to speed up their testing process would also find it valuable. Essentially, any scenario requiring frequent, accurate spectral measurements of light can benefit from this device.
