spectraval 1511

VIS Spectroradiometer

spectraval 1511 is a modern spectroradiometer for the VIS wavelength range, which can be used in stand alone mode or with a PC or laptop. It is equipped with a touchpad display and a SD card slot for in field measurements. The available interfaces for operation with the PC software JETI LiVal are USB and Bluetooth.

Diffusors

Standard diffusor (ACC 032)
The pure spectraval 15x1 measures in spectral Radiance mode. It is possible to convert it into a spectral Irradiance meter by attaching a diffusor.

In axis remote diffusor (ACC 015-length)
If the measurement needs to be done in locations with limited space conditions then the remote diffusor can be used. It is a diffusor which is coupled to the spectraval device by an optical fiber bundle. The measurement is done in axis to the fiber bundle. Different fiber lengths are available.

90° remote diffusor (ACC 035)
If the measurement needs to be done under limited space conditions and the in axis fiber coupled diffusor is not suited, then the 90° fiber coupled diffusor can be applied. Different fiber lengths are available.

Filters

Neutral density filter (ACC 033 OD1.0)
spectraval 15x1 can measure up to 100 000 cd/m² (typical white LED spectrum). An additional neutral density filter allows to shift the measuring range towards 10 times higher Luminance levels.

Dolby/realD filter cap pairs
The calibration of 3D projectors needs to be done through the right and left eye glasses. spectraval 15x1 can be equipped with caps containing the filters of Dolby (ACC 053) and realD (ACC 052) projection.  The usage of these filter pairs allows a precise measurement of 3D projections.

Straylight protection tube (ACC 046)
The straylight protection tube prevents the influence of surrounding light on Radiance measurements. It is mainly used for display measurements. The fixed length of the tube is 16 cm.
