Features

Collimated Beam Input

Depending on the beam divergence characteristics of the light source, Newport offers two different types of integrating sphere detectors – Divergent or Collimating. The 819C series are used for a collimated input beam, such as a laser beam. When the collimated beam is measured, the baffle needs to be placed between the first reflection off of the internal wall of the sphere and the detector. The baffle prevents direct radiation from the hot spot from hitting the detector, which allows the spatially integrated beam power measurement.

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.    

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.

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.

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.

Compatible Power Meters

Newport offers a comprehensive range of optical power meters from low cost, hand-held meters to the most advanced dual-channel benchtop meter available in the market.
