Edmund Optics NT30-933 Tech Spec™ Reflective Neutral Density Filter - BRAND NEW
$ 27.50 US  Please visit: www.torontosurplus.com for further details.
These filters have constant density values across the surface, while their transmission to reflection ratio varies with density. In stacks, the total density is the sum of each filter’s density. ND filters are used primarily for the attenuation of light over a wide spectral range. They are often used in laser and photometer applications, where excessive power can cause damage or inaccurate results. Orient mirrored side toward source at 0° angle of incidence.

SPECIFICATIONS(Common to ALL NT30 Series Filters):

• Material: Soda Lime Glass
• Dimensional Tolerance: +0.02"
• Design Wavelength: 400nm - 700nm
• Parallelism: <=3 arc min.
• Thickness: 0.0625" (1.6mm)

Melles Griot 03 BSD 027 Broadband Dielectric Cube Beamsplitters, Near Infrared
$ 95.00 US  Please visit: www.torontosurplus.com for further details.
Cube beamsplitters consist of matched pairs of right-angle prisms cemented together. The hypotenuse of one prism has a partial reflection coating. Cube beamsplitters have several advantages over plate beamsplitters: they are easier to mount; they are ideal for beam superposition; they exhibit less ghosting; and mechanical stress causes less deformation. Furthermore, the coatings are less likely to degrade over time because they are sealed into the body of the cube.

Broadband hybrid coatings are relatively insensitive to changes in polarization and wavelength. They are extremely polarization sensitive and should only be used with randomly or circularly polarized beams in applications where polarization is not important. Laser-line coatings are polarization insensitive only near the design wavelength (e.g., 632.8)

A black dot on the ground side of the prism indicates which prism has the partial reflector on the hypotenuse. The incident beam must enter the prism containing the partial reflector first.

SPECIFICATIONS:
• Typical Transmission Range (nm): 1300–1600
• Dimension: 12.7 ± 0.3 mm
• Clear Aperature: 11.4 x 11.4 mm
• Nominal R/T Ratio: 50/50
• Material: BK7 grade A fine annealed

Call for price  Please visit: www.torontosurplus.com for further details.
Optem’s Zoom 70XL Optical System represents the pinnacle in reliability when it comes to heavy-duty cycling.
With a 7:1 core zoom ratio, and a magnification range of 0.75X to 5.25X, the Zoom 70XL provides dependable, high-quality optics at an affordable price. The core Zoom 70XL boasts a numerical aperture range of 0.024 to 0.08 with minimum resolution of 240 lp/mm at maximum magnification.

THIS UNIT IS COMPRISED OF THE FOLLOWING MODULES:


• 39-96-10-309 Zoom 70XL: Upper Zoom Module, Manual Zoom w/ Iris Diaphragm. Iris diaphragms enable you to increase depth-offield and/or maintain constant image brightness.
  
  
• 29-60-84-310 Lower Fuction Module. This module provides a port for the injection of incident light and attaches Infinity-Corrected Objectives (not incl.) to your 70XL. I believe it can be used with the Dual Focus Vertical Illuminator, VSI 220 Illuminator, 220V/150W available from Thales-Optem.
  
  
• 378-811-2 Mitutoyo M Plan Apo Infinity-Corrected Objective. 50X ULWD, 0.42 Aperature, 20mm Working Distance, f=200. Significantly higher magnification and increased resolution is obtained by combining the Zoom 70XL Optical System with this infinity-corrected objective.
  
  
• 29-90-72 Optem Standard TV Tube 1.0X. The purpose of TV Tubes is to hold the camera at the correct image plane. Without it, you are left with a variable-focal-length lens of unknown magnification.
  
  
• 29-90-56 Optem DIN Eyepiece Adapter “C” Thread to Nikon and Olympus

OptoSigma 055-0360 Dove Prism - BRAND NEW
$ 148.75 US  Please visit: www.torontosurplus.com for further details.
Dove prisms have the useful property that they completely invert an image by 180 degrees. If the prism is rotated about its axis the image will rotate at twice the rate of rotation of the prism. Dove prisms provide the most convenient and most precise method of rotating a beam and their long length and square profile make them easy to mount in a cylindrical sleeve. These prisms are offered with a broadband multilayer anti-reflective coating on the end faces

SPECIFICATIONS & TOLERANCES:

• Dimensions: +0.2 mm
• Angular deviation: 1arcmin
• Surface flatness: λ /4 @ 633nm
• Bevel: 0.2 to 0.3mm typical
• Surface quality: 40-20
• Material: BK7, grade A

OptoSigma 055-0550 Penta Prism - BRAND NEW
$ 153.00 US  Please visit: www.torontosurplus.com for further details.
Penta prisms deviate an input beam by 270 degree (-90 degree) independently of the angle of incidence on the first surface. They are therefore useful as precise right angle mirrors which are insensitive to alignment. These penta prisms find many metrological applications.
These penta prisms are Anti-Reflection coated on the entrance and exit faces as well as being coated with protected aluminum and black paint on the internal reflection faces.

SPECIFICATIONS & TOLERANCES:

• Dimensions: +0.2 mm
• Angular deviation: 3arcmin
• Surface flatness: λ /4 @ 633nm
• Bevel: 0.2 to 0.3mm typical
• Surface quality: 40-20
• Material: BK7, grade A
• Coatings: Broadband AR on input/output faces protected aluminum and black paint on reflective faces
