FC/APC Fixed Aspheric Lens Fiber Collimation Packages

These FC/APC connectorized fiber collimation packages are ideal
for systems that are sensitive to back reflections. APC connectors
utilize a ferrule that has an 8 end face with an ultra PC
polish, typically leading to a return loss
greater than 60 dB.

Our fiber collimation packages are

designed to collimate a laser beam
propagating out of the end of an optical
fiber. These packages can also be used to
couple a free-space laser beam into an
optical fiber, provided that the
collimation package is correctly aligned
with respect to the input beam.

The RC08FC off-axis collimator creates a 90 angle between the incident and
reflected light. The mirror surface is coated with protected silver, which has
good reflection properties over a broad wavelength range, making it very
useful for systems with many different wavelengths. The RC08FC collimator
is pre-aligned to collimate a laser beam propagating from the tip of an FC/PC
connectorized fiber with diffraction-limited performance over a large
wavelength interval from less than 400 nm to more than 2000 nm. The
off-axis parabolic mirror is aligned such that the distance between it and the
fiber tip is equal to the focal length of the mirror. The off-axis parabolic
collimator is suitable for collimating the output from a single mode fiber. In
addition, it can be used to collect light from broadband sources and couple it
into a larger core multimode fiber.

Cables

Our line of pigtailed collimators has the fiber and AR-coated aspheric lens permanently glued inside a stainless steel housing. Each
collimator comes with one meter of single mode fiber and is aligned to collimate/couple light at the specified wavelength. Since the AR
coating encompasses a broad spectral range, it is possible to use this collimator at any wavelength within the coating range; however, the
divergence angle/coupling loss will increase as the wavelength is detuned from the design wavelength. Custom wavelengths are available
upon request.

Thorlabs offers a selection of gradedindex lenses for applications at 1300 nm

and 1560 nm. GRIN lenses are typically
used in fiber-based, passive and active
components to couple laser light from one fiber through a
free-space optical system, such as an optical isolator, and
back into another fiber to propagate through the rest of the
system. GRIN lenses can also be used for coupling the
output of laser diodes into fibers, coupling laser light onto
a detector, and collimating laser light.

Multichannel Fiber-Coupled Laser Source

Features

Ideal for Multichannel Fluorescence Imaging

4 Laser Output Channels
Independent Temperature Control Gives High
Temperature Stability
USB Interface
Many Wavelength Combinations Available

Thorlabs 4-Channel, Fiber-Coupled Laser Source provides easy access to multiple wavelengths of single mode
(SM) fiber-coupled light. The 4-channel laser source can accept many combinations of four SM fiber-pigtailed laser diodes; choose from the
following wavelengths: 406, 473, 488, 635, 658, 670, 785, 808, 850, 904, 980, 1310, 1550 nm. More wavelengths will be made available in
the future. Please check our website for the lastest details.
Each fiber-pigtailed laser diode is operated from an independent, high-precision, low-noise, constant-current source and temperature control
unit. An intuitive front-panel interface allows the user to view and set operating parameters for each laser. The display indicates the selected
channel number, output wavelength, operating power, and operating temperature of the laser diode.
This device includes a microcontroller to monitor the system for fault conditions and to fully control the lasers optical power and
temperature. The laser source includes a USB connection that allows remote adjustment of power, temperature, and enabling. On the rear
panel, analog inputs are available to modulate the lasers with
an external signal.
