The PTC-CH Series Chassis Mount Temperature Controllers deliver the precision performance and long-term reliability you expect from a Wavelength Electronics temperature controller. PTC-CH Series controllers are found in such diverse applications as particle and droplet measurement, manufacturing machine vision systems, biomolecular interaction analysis, and more. The PTC-CH controllers operate from a single power supply between 4.5 V and 30 V, and a selection of models allows you to optimize the current output level for your application. The linear bipolar controller drives a Peltier thermoelectric cooler or a resistive heater, and the chassis-mount package integrates easily into OEM applications.PTC-CH controllers interface with a variety of temperature sensors, and the bias current is adjustable in order to maximize controller sensitivity and stability for your application. The compact chassis-mount design simplifies heatsinking and requires minimal space. PTC-CH controllers are quick to configure for your prototype project, and there are no surprises when it's time to integrate the controller into the final design. Practical Features For Real-World Conditions Built-in features make your product more robust to real-world operating conditions and minimize your electronics overhead: If the optional remote temperature setpoint signal is lost, the controller defaults to a standard "safe" temperature setpoint (25ºC when a 10 k Ω thermistor is used). The safe temperature can be changed at the factory; call for details. An on-board trimpot is used to set the output current limit to prevent over-driving the TEC, and helps protect your load from thermal runaway situations. Proportional gain is easily adjusted with an on-board trimpot. Low temperature coefficient design remains stable across a wide range of ambient conditions.When used with Wavelength's laser drivers, such as the PLD Series, these temperature controllers provide stable and reliable performance that sets your system apart from your competitors' and keeps your customers satisfied.

Multi Mode, Square Core; 190 to 2400 nm; Core Size 100 to 1000 µm; Coating Acrylate, Nylon, Polyimide; Numerical Aperture 0.22Fiberguide’s Anhydroguide™ (ASQR) and Superguide™ (SSQR) series of square silica core, doped round cladding multi mode optical fibers excel in specific applications where traditional circular core fibers with Gaussian outputs are not ideal. The uniform “top hat” intensity profile these fibers provide are the desired output profile when performing tasks such as welding, photolithography, and spectroscopy. Square core fibers with round claddings are also excellent candidates for use in the laser diode industry, where the square shape enables a more ideal coupling match with the diode source. Fiberguide offers pure silica square core fibers with a fluorine doped cladding (0.22 NA) in a wide range of core diameters from 100 μm to 1000 μm. While the ASQR series features a low hydroxyl ion concentration (low OH) and works in the visible to IR range, SSQR variants with high hydroxyl ion concentration are suitable for the UV to visible range. Options include Acrylate, Polyimide and Nylon coatings as well as anti-reflective coatings like standard thin film coatings or RARe Motheye nano-surfacing. This anti-reflective technology enhances fiber transmission performance and significantly increases the damage threshold for your application over a large wavelength range. Key Features: Homogenized Output Distribution Top Hat Beam Profile Greater Capture Area than Round Fibers for Square Inputs Step Index Multi Mode Fibers Square Silica Core / Doped Round Cladding Coatings: Acrylate, Nylon, Polyimide Core Sizes: 100 to 1000 µm Typical Clad/Core Ratio (RD Clad): 1.2 (Diagonal to Clad OD) Wavelengths: SSQR (High OH) 190 to 1250 nm, ASQR (Low OH) 300 to 2400 nm Numerical Aperture (NA): 0.22 ±0.02 100% Proof Test Using 4-Axis Bend Method Applications: Laser Materials Processing; Astronomical Spectroscopy; Non-circular Diode Beam Coupling; Photolithography

The single mode (SM) or multi mode (MM) fiber is optically aligned to either the hermetically sealed InGaAs diode in TO-46 lens cap package enhancing the coupling efficiency and stability, or directly to the InGaAs diode mounted on a ceramic substrate. High responsivity and low capacitance make these devices ideal for very high bit rate receivers used in LAN, MAN, WAN and other high speed communication and monitoring/instrumentation systems. Angle polished connectors and custom packages are also available. For a solution involving FC connector and TO-46 attachment, users may consider either FCI-InGaAs-75-SM-FC or FCI-InGaAs-120-SM-FC in single mode operation. Similarly, the multi-mode variant is available in FCI-InGaAs-120-MM-FC using 62.5/125 µm fiber. The back-reflection of -30dB typical is to be experienced in multi mode (MM) based solutions. Key Features: High Speed High Responsivity Spectral Range 900nm to 1700nm Low Back Reflection Applications: Very High Bit Rate Receivers Used in LAN, MAN, WAN; High-speed Optical Communications; Gigabit Ethernet / Fibre Channel; SONET / SDH, ATM; Optical Power Monitoring / Instrumentation
