Specifications

Features

Divergent Beam Input

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.

819D integrating sphere configuration is ideal for divergent beam source such as an output beam from a laser diode.

Integrating Sphere Accessories

Newport offers accessories that are compatible with our integrating spheres to build a complete integrating sphere system. Various adapters are available to change port frame diameter, reduce an input port's clear aperture, measure fiber optic power, connect lens tubes and mount sensors. Port plugs to block an unused sphere port are also available.

Why Integrating Sphere Detectors?

One of the major advantages of using an integrating sphere is to diffuse the input beam so that the detector readings are insensitive to errors caused by detector positioning or problems associated with overfilling, or saturation of the active area of the detector. The detector should see a completely diffused input field. Then, a key technical consideration, when deciding which configuration one has to choose, is whether the input beam will directly hit the detector, influencing the optical power at the detector. For this purpose, each integrating sphere includes a baffle. For more information, please refer to our Integrating Sphere Fundamentals and Applications Tutorial. 

Factors that Affect Maximum Measurable Power

The maximum measurable power of photodiode sensors is dependent on several factors such as the wavelength of incoming light, photodiode current output saturation, temperature, use of an attenuator and a power meter's maximum current input value. Newport provides maximum power specifications based on the power meter models, with and without an attenuator, and wavelength-dependent maximum power level. With these factors affecting measurable power in mind, choosing the proper detector for your application is critical.

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.

UV, Visible, and IR Wavelength Ranges Available

The spheres with a silicon photodiode are suitable for measurements ranging from 400 – 1100 nm, while the models with an InGaAs detector are suitable for approximately 800 – 1650 nm range. The UV version is optimized for wavelengths between approximately 200 - 400 nm, even though it is calibrated up to 1100 nm.

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.

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.

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.    

Note on User Modification of Configuration

Note that the system calibration is no longer valid if any component is changed from the original calibrated configuration. For a very high power level, elevated temperature of the integrating sphere system can affect the measurement accuracy, so the sphere must be properly cooled. Check with Newport for the complete list of integrating sphere detectors. For individual integrating spheres and accessories see Integrating Spheres and Accessories.
