Handheld Photometer

The HLMS-200P is an easy-to-use, precision photometric instrument designed for use in the field, laboratory or on the production floor.

The HLMS-200P instrument measures luminous flux from sources such as LED

Light Emitting Diode
s, small lamps and fibre illuminators. The instrument's photopically filtered silicon detector provides maximum sensitivity at low light levels. Sensitivity over five full decades provides the ability to measure from 0.05 to 7,000 lumens. A calibration certificate with calibration traceable to National Institute of Standards and Technology (NIST) is included.

The HLMS-200P is compact, lightweight, and rugged with a handle-grip enclosure and a built-in microprocessor that performs several functions at the touch of a button.

Data is instantly displayed on an easy-to-read 4-digit front panel LCD display. Simple push button controls are easily accessible and clearly labelled on the front panel. The instrument is powered by a 9V battery and is calibrated to display lumens.

General Purpose Spheres

General Purpose Spheres

Clients can choose spheres by selecting size, ports and reflectance material.
Technology From: Labsphere

General Purpose Spheres

These General Purpose Spheres provide greater configuration flexibility than ever before. Clients can choose spheres by selecting size, ports and reflectance material. The addition of a wide range of interchangeable accessories including light sources, assemblies, port reducers and more allows for an endless number of application solutions.

This flexibility allows customers to create a uniform source or light measurement system, or modify an existing system in a matter of minutes. A variety of system calibration options enable systems to be customised for application specific tasks.

Labsphere's sphere design features sturdy port frames, easy access mounting options and quick-change accessory options meeting a multitude of requirements. Their dedicated Calibration Lab provides calibration options to ensure systems are customised to meet specific application requirements. Clicking on the system software recalibrates as components are changed.

These spheres are offered with Spectraflect®, Spectralon® or Infragold® coating which combines a highly reflective surface with nearly perfect Lambertian reflectance. Both durable and highly stable over time, these coatings ensure optimal integration of light over the lifetime of your sphere.

All of Labsphere's products are created in an ISO

International Organization for Standardisation
9001 registered environment and provide NIST
National Institute of Standards and Technology
traceable results upon calibration. Once the configuration has been selected, qualified engineers and a support staff are on hand to help you with your specific application needs.

UV Sphere Assemblies

UV Sphere Assemblies

The sphere assemblies are provided with M4 or M6 (or 1/4-20) centre mount plates for easy mounting to an optical bench. A selection of optional mounting posts and bases are available.
Technology From: Labsphere

UV Sphere Assemblies

Warsash Scientific offer a series of integrating sphere assemblies featuring magnesium fluoride over aluminium (MgF-Al) coating process. The DUV

Deep Ultraviolet
Series Integrating Spheres are available in 50mm (2"), 100mm (4") and 150mm (6") diameter spheres with a choice of three or four ports. Each sphere assembly includes a baffle, SMA Adapter, TO5 Detector Adapter, and Port Plugs coated with a MgF-Al DUV coating.

The sphere assemblies are provided with M4 or M6 (or 1/4-20) centre mount plates for easy mounting to an optical bench. A selection of optional mounting posts and bases are available.

Aluminium has a high intrinsic reflectance value in the UV

Ultraviolet
region above 100nm. The protective overcoat of magnesium fluoride helps protect the aluminium and optimises its reflectivity. The MgF-Al coating is quickly becoming an industry and national laboratory choice of coating for applications in the UV wavelength regions. The coating is efficient for applications covering the 100 to 400nm range and is more stable than PTFE
polytetrafluoroethylene
materials in that region. The deep UV coating provides three major advantages for use in the 100 to 400 nm region:

  • Non-fluorescence
  • Damage Resistance
  • High Stability

The coating has a reflectance of >90% over the wavelength region from 1000 to 2500nm, and may also be used effectively for many Vis

Visible
and NIR
Near Infrared
applications.

Warsash Scientific and Labsphere provide detailed information on the care and handling of the DUV spheres to help extend their lifetime and to ensure you get accurate, repeatable measurement results.

Key Features
  • High Stability for UV Applications Ranging from 100 to 400nm
  • No Fluorescence
  • >90% Reflectance from 1000 to 2500nm

Laser Power Measurement Spheres

Laser Power Measurement Spheres

Integrating sphere measurements of laser power also eliminate polarisation effects often associated with filter attenuation techniques.
Technology From: Labsphere

Laser Power Measurement Spheres

Independent of beam geometry and without the need for auxiliary optics, Laser Power Measurement Spheres are ideal for collecting the total radiant power emitted by highly divergent sources, such as laser diodes as well as a collimated laser beam. Accurate, repeatable measurements may be performed quickly and easily without painstaking positioning and alignment procedures. Integrating sphere measurements of laser power also eliminate polarisation effects often associated with filter attenuation techniques.

The liquid-cooled Laser Power Measurement Spheres include three sizes of liquid cooled integrating spheres designed for performing power measurements of high power pulsed and continuous wave lasers. Coated with Infragold® High Reflectance Coating for measurements over the 700nm — 20µm wavelength range, the liquid-cooled design can handle a maximum power density of 2kw/cm2 (CW for 1 second exposure at 10.6µm) while greatly reducing the self-emission that would result from an un-cooled sphere.

Laser Power Measurement Spheres are offered for applications in the wavelength regions from UV-Vis-NIR

Ultraviolet-Visible-Near Infrared
to the NIR-MIR
Near Infrared-Mid Infrared
. Each laser power measurement sphere is designed to accommodate standard Labsphere detector assemblies.

Key Features
  • Laser Power Measurement Spheres
  • Results Independent of Beam Geometry up to 40° Half Angle
  • Efficiently Collects Total Power from Highly Divergent Sources
  • Ability to Mount Two Different Detectors or Spectrometers Simultaneously
  • Attenuates the Signal to Avoid Detector Saturation
  • Liquid-Cooled Laser Power Measurement Spheres
  • Efficient Heat Removal System for High Power Laser Measurements
  • A Laser Target Included with the Sphere to Disperse the Source Energy
  • Coolant Type Can Be Chosen by the User

Reflectance/Transmittance Spheres

Reflectance/Transmittance Spheres

Technology From: Labsphere

Reflectance/Transmittance Spheres

Reflectance/Transmittance Sphere Assemblies constitute one of the most basic reflectance measurement products and can be used to measure the reflectance or transmittance of a wide variety of sample mediums. Offered in two standard designs, each sphere is available in one of two reflective coatings; Spectraflect®, a highly diffuse reflective coating effective over the 300 - 2400nm range and Infragold®, designed for use in the 0.7 - 20µm wavelength range.

The Reflectance/Transmittance Spheres feature five 25mm (1") diameter ports to accommodate sample and reference beams necessary for a 9° double beam geometry, as well as port plugs required for 9° single beam geometry. A 13mm (0.5") detector port is located at the top of the sphere. A specular light trap is included for specular subtraction methods.
