PA-XXX
Port Adapters

A port adapter is a black anodized aluminum cylinder that mounts onto a port frame (PF-XXX). It serves as a structure for mounting customer accessories and has two thumb screws oriented at a relative angle of 90 for securing accessories. A port adapter will also mount onto a port frame equipped with a port frame reducer.

LTRP-XXX-C, M
Light Traps

A light trap is a cylindrical cavity with an interior structure that is designed to absorb the incident radiation that enters through its open end. The cavity is coated with an optical black coating that exhibits an absorptance of greater than 97% over the wavelength range from 250 to 2500nm. Labsphere offers two light trap designs for use with integrating spheres. They both achieve higher absorbtance than the optical black coating alone because their cavity designs have been optimized to geometrically trap more of the incident radiation. An LTRP-XXX-C light trap mounts on a port frame (PF-XXX). The conical interior of the cavity is designed to maximize the absorbtance of the light trap. Absorptance exceeds 99% from 250 to 2500 nm. An LTRP-100-M light trap is designed for use with the sample holder accessory. It inserts into the cup of the sample holder to trap the transmitted component when measuring reflectance of translucent samples. It may also be used to eliminate the non-scattered component of a transmittance sample. Absorbtance exceeds 98.5% from 250 to 2500 nm.

Laser Targets

A laser target is a conical shaped port plug that mounts onto a port frame (PF-XXX) to reduce the power density of the first strike laser beam.  

HLT-200- IG
Laser Targets

A 2 inch diameter hemispherical liquid-cooled laser target is a port plug that mounts onto a port frame (PF-XXX) to reduce the power density of the first strike laser beam.

SH-100-0, -8 SF, IG
SAMPLE HOLDERS

A sample holder mounts onto a 1 inch port frame (PF- 100) or port frame reducer (PFR-100) and is designed to hold reflectance and transmittance samples. The sample holder may be disassembled such that only the mounting plate remains if it is necessary to mount large samples. Sample holders are available with Spectraflect (SF) or Infragold (IG) coatings. The SH-100-0 SF, IG holds the samples flush to the sphere wall at the port such that the radiation striking the port at normal incidence also strikes the sample at normal incidence. The minimum sample size must exceed 0.875 inch, the clear aperture of the sample holder. The SH-100-8 SF, IG is a skewed design that holds the sample flush to the sphere wall at an angle of 8 with respect to the beam entering the port at normal incidence. The minimum sample size must exceed 0.687 inch. Sample holders are designated by a four part order number. For example, SH-100-8-SF designates a sample holder which, when mounted onto a 1 inch diameter port frame, holds a sample at an angle of 0 to the incident beam, SF designates Spectraflect coating.

The FH-050-050 filter holder mounts onto a 0.50 inch port frame (PF-050). Any of the other accessories that mount onto a PF-050 may also be mounted onto the filter holder. The filter holder accommodates filters 0.50 inch in diameter and up to 0.375 inch thick.

The FH-100-200 filter holder mounts onto a 1 inch port frame (PF-100). Any of the other accessories that mount onto a PF-100 may also be mounted onto the filter holder. The filter holder holds 2 inch square filters up to 0.375 inch thick.

DETECTOR HOLDERS

A detector holder mounts onto a 0.50 inch port frame (PF-050). It is fitted with a Delrin insert that accommodates a detector case. The DH-050-T05 detector holder accommodates a T05 case and a DH-050-T08 accommodates a T08 case.
