The 819D-SL-5.3-CAL2 is a NIST traceable calibrated integrating sphere detector using a 5.3 inch integrating sphere with a high performance silicon photodetector. The input port size is 0.5 in. diameter and the wavelength range is 400 – 1100 nm. For a very high power level, elevated temperature of the integrating sphere system can affect the measurement accuracy so the sphere must be temperature controlled. Calibration is performed with and without attenuator.
Divergent Beam Input
819D integrating sphere configuration is ideal for divergent beam source such as an output beam from a laser diode.
Depending on the beam divergence characteristics of the light source, Newport offers two different types of integrating sphere detectors – Divergent or Collimated. The 819D series detectors are designed for a diverging light source, including laser diodes, lensed LEDs and lensed lamps. In the 819D series, the baffle is placed between the input port and the detector, so that the undiffused beam does not hit the detector directly.
Tightest Calibration Uncertainty
Calibrated integrating sphere detectors are available with a low noise Si, UV-enhanced Si or an InGaAs photodiode. The available sphere sizes are 2”, 3.3” or 5.3” diameters. To maintain accuracy and guarantee performance Newport recommends annual integrating sphere detector calibration. Every product includes a full spectral response calibration utilizing NIST-traceable standards calibrated with high-precision equipment maintained in Newport’s optical detector calibration facility. Tight calibration facility and process control allows the tightest calibration uncertainty in industry. Each detector is shipped with the calibration data, which is electronically stored inside the detector's EEPROM. A certificate of calibration as well as the actual calibration curves and data are shipped with each product. To maintain accuracy and guarantee performance Newport recommends annual photodiode detector calibration.
Advanced –CAL2 Models
Advanced models that end with a “-CAL2” suffix feature a detector that has an integrated thermocouple and OD1 attenuator. When these models are connected to power meter models 1830-R, 1918-R, 1936-R or 2936-R, they will automatically recognize both the attenuator “on/off” position as well as the detector head temperature. The advanced models are designed for added convenience and ease of use.
Post-Mountable for Accurate Measurements
To ensure accurate measurements, it is recommended to mount these integrating spheres securely. One way to do so is by mounting them on an optical post.
SMA Fiber Adapter on the North Pole
All the spheres come with an SMA fiber adapter on the North pole as a standard feature, allowing a small amount of light pickoff for wavelength measurement or any further analysis without affecting the overall system calibration. All sphere detectors are calibrated with the adapter already installed.
It is important to determine whether enough signal can be sent to the spectrometer or a monochromator. A rough estimate on how much light will couple to the optical fiber can be obtained by taking the ratio between the core area or the effective mode area of the fiber and the surface area of the sphere, which can be very small. We recommend using a spectrometer that accepts at least 400 to 600 um diameter fiber input.
