FemtoViewer is a high performance near IR viewer optimized for applications involving the alignment of near-infrared Ti:Sapphire laser beams. Titanium-doped sapphire (Ti:Sapphire) has become by far the most common laser material for the generation of ultrashort pulses. The wavelengths in which Ti:Sapphire crystal will produce gain stretch from 660nm to 1180 nm. A bandwidth of over 400 nm in the near IR region makes Ti:Sapphire a very attractive material for use in tunable laser sources and generation of very short pulses with a broad tuning range.

Beacon Femtosecond Optically Gated Fluorescence Kinetic Measurement System - request a quote  - pdf Beacon together with Trestles Ti:sapphire oscillator, second and third harmonic generators. Femtosecond optical gating (FOG) method gives best temporal resolution in light-induced fluorescence lifetime measurements. The resolution is determined by a temporal width of femtosecond optical gate pulse and doesn't depend on the detector response function. Sum frequency generation (also called upconversion) in nonlinear optical crystal is used as a gating method in the Beacon femtosecond fluorescence kinetic measurement system. We offer Beacon-DX for operation together with Ti: sapphire femtosecond oscillators and Beacon-DA for operation together with femtosecond amplified pulses.

AOTF Infrared Spectrometer Del Mar Photonics offer a handheld infrared spectrometer based on the acousto-optic tunable filter (AOTF). This instrument is about the size and weight of a video camera, and can be battery operated. This unique, patented device is all solid-state with no moving parts. It has been sold for a wide variety of applications such as liquid fuel analysis, pharmaceutical analysis, gas monitoring and plastic analysis. Miniature AOTF infrared spectrometer uses a crystal of tellurium dioxide to scan the wavelength. Light from a light source enters the crystal, and is diffracted into specific wavelengths. These wavelengths are determined by the frequency of the electrical input to the crystal. Since there are no moving parts, the wavelength scanning can be extremely fast. In addition, specific wavelengths can be chosen by software according to the required algorithm, and therefore can be modified without changing the hardware. After the infrared radiation reflects off of the sample, it is converted into an electrical signal by the detector and analyzed by the computer. Del Mar Photonics is looking for international distributors for RAVEN - AOTF IR spectrometer for plastic identification and for variety of scientific and industrial collaborations to explore futher commercial potential of AOTF technology.

Thermal imaging The IR-viewers can be used to image the thermal radiation of objects above 600°C (such as kilns, furnaces or solder pots). Objects in this temperature range (and hotter) emit enough infrared radiation in the 0.8-1.5 micron wavelength range to be imaged.

The Field Selector Mechanism (FSM) design consists of a Zerodur mirror, bonded to an Invar 36 mirror support, which is constrained in four degrees of freedom (DOF) by a plate spring and a central strut. The former constrains the two in-plane translational DOF of the mirrorand rotation around the optical axisof the mirror, while the latter constrains the mirror in the optical direction, normal to the mirror surface. The remaining two DOF, the tip and tilt directions, are actuated by two actuators, which are located at the edge of the mirror support and are spaced 90° apart around the mirror normal.

High performance infrared monocular viewers are designed to observe radiation emitted by infrared sources. They can be used to observe indirect radiation of IR LED's and diode lasers, Nd:YAG, Ti:Sapphire, Cr:Forsterite, dye lasers and other laser sources. IR viewers are ideal for applications involving the alignment of infrared laser beams and of optical components in near-infrared systems. The light weight, compact monocular may be used as a hand-held or facemask mounted for hands free operation.

Note that the absolute accuracy requirement contains dynamic requirements on the pointing jitter of the mirror, as well as on the absolute pointing knowledge with respect to a fixed reference. Furthermore, although the required stroke and step is not equal in tip and tilt direction, the FSM is designed symmetrical such that the largest stroke can be attained in both directions.

Absolute accuracy is achieved with two differential inductive sensor pairs. Friction in the spindle drive is overcome by creating a local velocity control loop between the spindle drives and the shaft encoders. Accuracy is achieved by using a cascaded low bandwidth control loop with feedback from the inductive sensors.

Standard IR viewers have spectral response up to 1300nm. IR viewers with extended spectral range are available: models 1700 (with sensitivity up to 1700nm) and model 2000 (with sensitivity up to 2000nm).

Two spindle drives actuate the mirror, using a stiffness-reduction transmission to increase resolution: when rotating the motor, the nut compresses a soft spring. The soft spring exerts a force against a high stiffness spring, which is connected to the mirror support. As the stiffness ratio between the soft and stiff spring is 1:22, motion of the nut results in a factor 22 smaller motion of the mirror. This principle increases the resolution dramatically, while compromising only slightly in the dynamic behavior of the FSM; the first eigenfrequency of the stiff spring is 135 Hz.
