The Jeti specbos 2501 is a true Spectrometer that delivers high quality results, with very accurate measurement capabilities on all display devices, and is a further development of the successful specbos 1211-2 models as well as the spectraval series.
- ColourSpace INF/XPT/PRO & HTX/HTP
- 7+mm Spot Size
- 1nm Wavelength Resolution
- 4nm Spectral Bandwidth (2nm HiRes version)
- 0.2 to 100,000 cd/m2
- Target Spot Laser
Overview
The Jeti specbos 2501 is fast and highly sensitive, covering the wavelength range from 350 to 780nm (optional 380-100, or 200-1000), and includes a mechanical shutter for dark signal compensation.
The Jeti 2501 can be ordered with a Cosine Diffuser, which is optional as for display calibration use this is normally unused.

Recalibration/Re-certification
The specbos 2501 should be factory recalibrated/re-certified every year to two years, depending on usage and storage, or when obvious issue are found (after physical shock to the probe for example).
Contact Jeti to schedule recalibration/re-certification.

ColourSpace Integration
As with all probes, operation and function is controlled via the Probe Options menu, accessed via the Profiling window, with the left-hand side of the menu providing generic probes settings, and the right-hand side settings specific to the specbos 2501.
Sync Frequency
Sync Frequency defines the sync frequency of the probe, with Auto being the default, although Manual can be used if the refresh rate of the display is known.
(If the Jeti shows an adoption error, the frequency will need to be manually set to the video frame-rate.)
Settings
Calibration Settings provides generic probe settings.
Average Low Light
Average Low Light is a probe generic option, that averages multiple readings in low-light situations using an advanced algorithm built into ColourSpace. The algorithm varies based on the probe in use to provide the best possible results.
Enable Visible Feedback
Enable Visible Feedback enables the inbuilt laser pointer, assisting with probe alignment when profiling screens from a distance.
Probe Adjustments
Probe Adjustments are generic probes settings, with consistent operation regardless of the probe in use.
Configure Matching
Probe Matching is really unnecessary with the Jeti, as it is a Spectrometer.
The options is provided on a Why Not basis...
Offset
Probe Offset enables a user to manually enter offset values for different probes/display combinations.
Perceptual Colour Match is a preferable approach.
Extra Delay
Extra Delay sets a delay time after the patch has changed before probe measurement starts, and can be set automatically via the Auto button, and manages signal path delays in the image pipeline.
When using the Auto option, Average Low Light should not be enabled.
