Product Name: 74-series Lens Fixtures
Product Description
The 74-series Collimating Lens Fixture is the common fiber optic-coupled lens
fixture used throughout our extensive line of sampling accessories. Accessories
include lenses of fused silica (74-UV), BK-7 glass (74-VIS) or a doublet of
BaF10 and FD10 glass (74-ACR)
74-UV Collimating Lens (200-2000 nm)
The 74-UV has an f/2 fused silica lens for 200-2000 nm. When focused for
collimation, beam divergence is 2° or less, depending on fiber diameter. The
74-UV can be adjusted for UV-VIS or VIS-NIR setups.
One white dot on the barrel identifies the 74-UV.
Price: $159
74-VIS Collimating Lens (350-2000 nm)
The 74-VIS -- the basic lens fixture in an LS-1 Light Source -- has a BK-7 lens
suitable for the VIS-NIR. These single-lens systems have the disadvantage of
chromatic aberration, due to dispersion or variation in refractive index with
wavelength.
One yellow dot on the barrel identifies the 74-VIS.
Price: $159
74-ACR Collimating Lens (350-2000 nm)
The 74-ACR has two optical elements cemented together to form an achromatic
doublet, optimized to correct for spherical and chromatic aberrations.
Two yellow dots on the barrel identify the 74-ACR.
Price: $199
74-DA Collimating Lens (200-2000 nm)
The 74-DA Direct-attach Collimating Lens screws on to a spectrometer's SMA-905
Connector for increased light throughput. The lens collects collects collimated
light in a straight path of open air and focuses it on to a spectrometer's slit.
Price: $159
Features
- Stainless steel with black oxide finish
- Inner barrel threaded for SMA 905 Connectors (1/4" OD FC barrels are
available)
- Adjustable focusing
- Adjustable from converging to diverging FOV (~45°) is possible
Technical Tips
- The divergence (a) of a beam focused using a single lens is tan(a) = d/f
where f is the focal length of the lens and d is the aperture or fiber
diameter.
- The optical fibers Ocean Optics specifies for use with its spectrometers
and light sources have FOV of ~25° -- an acceptance angle that may not be
optimum for some experiments. Collimating lenses are adjustable, allowing the
user to establish FOV angles from near- collimation (~ 0°) to ~45°.
- Be careful when adjusting collimating lenses, as inaccurate focusing of
the lens can result in a de facto change of the sample path length.
