- The PR-740 (spectral range 380 - 780 nm) and PR-745 (spectral range 380 – 1080 nm) SpectraScan spectroradiometers have the two most wanted attributes of any light measuring instrument - superior sensitivity and speed. For the PR-740, the minimum measureable luminance is 0.000005 footlamberts (0.000015 cd/m2). For the pr-745, 0.0000025 footlamberts (0.0000075 cd/m2). These two world-class instruments also introduce a new feature to the SpectraScan line - variable spectral bandwidth. Most self-scanning spectroradiometers feature a single system bandwidth. The Variable Bandwidth option provides three bandwidths, selected from the instrument menu or from a PC using Remote Mode Commands or SpectraWin 2 software. Bandwidth sizes include 2, 4 and 8 nm for the PR-740 or 4, 8 and 14 nm for the PR-745. This option is useful when it is necessary to resolve the spectral profile of narrow band sources with more precision (using a smaller bandwidth) or get more throughput for broadband sources (using a larger bandwidth) without changing instruments or measuring spot size.
- Connectivity
A wide selection of interfacing options, USB, RS232 and Bluetooth wireless, adds convenience and ease when communicating with and controlling the PR-74ol745. With the Bluetooth option, the instrument will communicate for up to 100 feet (30.5 m) away from the base - ideal for situations where cabling is not possible.
- Variable Spectral Bandwidth
The PR-740/745 introduces a new feature to the SpectraScan line - variable spectral bandwidth. One of 3 bandwidth settings (2. 5 or 8 nm for the PR-740 or 4, 8 and 14 nm for the PR-745) can be selected regardless of the measuring aperture being used. This lets the user change the bandwidth without changing apertures - or instruments.
- Versatility
The PR-740/745 provides unsurpassed flexibility with the world's largest selection of optical accessories. It is the only instrument in its class that can measure radiance/luminance, irradiance/illuminance, radiant flux/lumens and radiant intensity/candelas simply by changing accessories.
