OL IS-670 6-Inch Integrating Sphere
The OL IS-670 consists of a 6-inch diameter, PTFE coated, integrating sphere with a 90° entrance port to exit port configuration. The
integrating sphere can easily be mounted at the entrance port of the OL Series Monochromators and can be rotated 360° for horizontal
or vertical viewing. Either configuration maintains the nearly ideal cosine response of the OL IS-670 (please refer to
Application Note A9 for further details).
The design of the sphere and the geometries of its components (entrance port, baffle, etc.) enable the OL IS-670 to achieve a near-perfect cosine response.
The optional OL ISA-2DW 2" diameter dome window is available as a protective window for then entrance port of the OL IS-670. The OL ISA-2DW is made of uv-grade fused silica which transmits over the entire 200 to 2500 nm range. The window helps protect the white coating from dust, dirt and other contaminants. The window's dome shape prevents adverse effects to the sphere's near-perfect cosine response. A flat window is also available for unique applications where cosine response is not a critical factor.
The near-perfect cosine response is essential when measuring radiant flux of large area sources, measuring incident flux over a 2p steradian field of view, and certain types of intense arc lamps, solar simulators, and sunlight.
The OL IS-670, which is coated with a PTFE based powder, is useful over the wavelength range of 200 to 2500 nm.
OL IS-1000 Integrating Sphere Reflectance/Transmittance Attachment
The IS-1000 is a 6-inch integrating sphere reflectance/transmittance attachment for measuring diffuse spectral reflectance and transmittance of various materials over all or part of the entire wavelength range of 250 to 2500 nm. It is especially useful for measuring optical properties of leaves. The IS-1000 is used in combination with the OL Series 752-10 Plug-In Irradiance Standards and the OL Series 750 or Series 754 Spectroradiometers.

OL 730-8 Reflex Microscope
The OL 730-8 Reflex Microscope converts the Optronic Laboratories' series of light measuring instruments into either microphotometers, microradiometers, or microspectroradiometers. The reflex microscope enables these instruments to measure the luminance, radiance, or spectral radiance of very small, diffusely emitting sources. The useful spectroradiometric wavelength range with the achromatic lens is 360 to 1100 nm.

OL 730-9A and OL 730-9Q Reflex Telescopes
The OL 730-9A and OL 730-9Q Reflex Telescopes enable the Optronic Laboratories' series of light measuring instruments to operate either as telephotometers, teleradiometers, or telespectroradiometers. The reflex telescope is used to measure the luminance, radiance, or spectral radiance of uniform, diffusely emitting light sources.
OL 730-9A
The OL 730-9A consists of an achromatic, 66 mm lens in a rack and pinion focusing mount, a baffle tube, and a reflex viewer compartment with zero parallax viewing. The reflex viewer has a 3 element, orthoscopic eyepiece which yields an 8X magnification. The wide-field eyepiece has a precision reticle with ten concentric circles ranging from 1 to 10 mm. Three apertures producing FOVs (field of views) of 1.5° ,1° , and 0.5° are standard. The useful wavelength range of the OL 730-9A is 360 to 1100 nm.
OL 730-9Q
The OL 730-9Q is identical to the OL 730-9A except for the substitution of a quartz lens for the standard achromatic lens. The quartz lens extends the useful wavelength transmission range from beyond 250 nm in the UV to 2.5 µm in the IR. However, this is accomplished with a slight deterioration of the focused image due to chromatic aberration.

OL740-4P Off-Axis Parabolic Telescope (OL 750 Systems only)
The OL 740-4P Off-Axis Parabolic Telescope is designed to facilitate a broad range of radiometric measurements over the entire UV to IR wavelength range. The telescope can be interfaced to the entrance port of the OL Series 750 Monochromator system to measure spectral irradiance or radiance of collimated, point or diffusely radiating sources, or it can be interfaced to the exit port to obtain a highly collimated, monochromatic flux level and used to calibrate various detectors or radiometer systems. The telescope may also be interfaced to the OL 480 Blackbody Source to obtain a collimated, broadband source at various blackbody temperatures, or to the OL 300 Low Light Calibration Source (with starlight shaping filter) to obtain a collimated star standard.
