The Sekonic SpectroMaster C-700R is the measures every light source (LED, HMI, Fluorescent and the natural light spectrum) PLUS wireless
flash. In addition, with its CMOS linear sensor, the SpectroMaster C-700R makes it possible to capture spikes in light source output, especially fluorescent and
LED lighting, providing unmatched colour measurement accuracy.
With a touch of your finger you can select ambient or flash colour temperature measurement with just the filter compensation value you need. Balancing multiple light sources for clean neutral lighting has never been so quick and accurate. Popular light balancing and colour correction filter brands have already been loaded to provide a familiar and convenient workflow.
Sophisticated features such as selective wireless flash triggering (C-700R only with PocketWizard transceivers, Sold Separately) truly offer photographers the first advanced Spectrometer designs with still and motion shooters in mind. When your work demands motion, the C-700 really shines with uncompromising precision measurement and correction for LED, HMI and fluorescent lighting. Viewing and comparing the spectral energy distribution of your measured light sources provide real time validation of what your lightings are capable of doing and what you need to do to achieve your goals. Whether your white balancing, Multi-light balancing, creating colour lighting effects or striving for accurate colour reproduction, the C-700R is the ultimate colour control tool.
Spectrometer (Color Meter):
Measures Colour Temperature (K)
Provides Colour Compensation Data
Provides Light Quality Information such as CRI and Spectrum distribution graph
Utilizing a CMOS Linear Image sensor, the C-700R SpectroMaster measures any light sources with repeatable and precise accuracy.
Precise measurements of LED, HMI, Fluorescent, Tungsten, Electronic Flash and Natural Light Spectrum set the C-700R apart from other spectrometers.
The C-700R is the only spectrometer to offer wireless radio triggering (with PocketWizard transceivers, Sold Separately) and measuring of electronic flash units. Selective zone control provides specific triggering and measuring of a flash group or unit.
Intuitive colour touch screen offers easy navigation through Spectral distribution, lighting comparisons, CRI color data and more.
CMOS Linear Image Sensor:
The heart of the C-700 series SpectroMaster is the CMOS Linear sensor. It starts with the carefully designed and manufactured light diffusion receptor, which evenly distributes the light on to the internal sensor. A fiber optic internal rod tunnels the captured light passing it through Infrared cutting filters and heat-absorption glass to avoid any aberrations during the actual measurement and evaluation process. A collimated lens focuses the light into a narrow beam and finally a Douser releases the light onto the CMOS (Complementary Metal-Oxide-Semiconductor) linear image sensor for measurement.
Precise Measurement of All Light Sources:
Precise measurements of LED, HMI, Fluorescent, Tungsten, Electronic Flash and Natural Light Spectrum set the C-700 series apart from other spectrometers.
It can measure the true colour temperature of a light source from 380 to 780 nanometers (nm). What makes the C-700 series truly unique and exceptional is its ability to not only measure conventional continuous light sources but also electronic flash, in addition to emerging light sources. Utilizing its measuring and evaluating process, it can capture spikes in light sources, especially those from fluorescent and LEDs, providing unmatched colour measurement accuracy in the an affordable end-user friendly spectrometer designed especially for the photo/video industry.
Wide Illumination Range:
With a measuring range of 1 to 200,000lx (0.09 to 18,600fc) and 20 to 20,500lx/s (1.86 to 1,900fc/s) it offers a significant sensitive range in both continuous and flash output measurement.
Cinematographers will especially appreciate the quick and easy selection from lux to foot-candles or lux seconds to foot-candle seconds. Balancing light ratios or checking light intensity on the set can be done quickly. Industrial users monitoring light levels to avoid excessive light exposure on museum pieces or plants in a
horticultural environment will benefit from its simplicity of use and conformity to Japanese Industrial Standards (JIS).
Note: Models sold in some countries do not display illuminance and exposure in "fc" or "fc/s" due to legal restrictions.
The only spectrometer to measure wireless flash, the C-700R features a built-in PocketWizard® wireless triggering system. Electronic flash units can be measured remotely. Flash units can be triggered up to 100 feet (30 meters) away using the wireless triggering radio and compatible PocketWizard® receivers (Sold Separately). A convenient PC connector or cordless flash mode is also available to trigger flash units.
Various Display Modes with Intuitive Color Touch Screen:
The C-700's 4.3" large colour touch dot-matrix screen displays various modes and functions in a logical and intuitive layout. The main selection screen displays the quick icons for the following Display Modes:
Spectrum Camera Filter
C-700/C-700R Expanded Measurement and Compensation Values:
The C-700 series SpectroMaster offers a wide selection of measuring values and various compensation solutions. Access to these values can be quickly selected by a tap of your finger on the appropriate icon
Up to 99 readings can be memorized.
Contrast Function to show the difference between standard value and currently being measured value.
Dark calibration can be done by turning the Light Selection Ring to set to the dark calibration position or perform it from Setting menu without a cap to cover the light receiving section.
Two AA batteries or rechargeable batteries conveniently provide portable power. A USB cable provides continuous power during measurement, firmware updates, data uploads or downloads and custom settings.
