10：90 2x2 1064nm Polarization Maintaining Fiber Coupler FC/APC

These 2x2 polarization-maintaining (PM) fiber couplers are designed for the wavelength range of 460-2200 nm, with selectable coupling ratios of 50:50, 75:25, 90:10, or 99:1. The 2x2 couplers are bidirectional and can be used for signal splitting and combining (see the 2x2 coupler example label). The polarization-maintaining couplers are fabricated using panda-type PM fibers, enabling them to maintain high polarization extinction ratios (PER) when light propagates along the slow axis of the fiber. As shown in the right diagram, stress rods are aligned parallel to the fiber core and apply stress, creating birefringence within the fiber core to achieve polarization-maintaining functionality. Typical applications of polarization-maintaining couplers include optical sensors, optical amplifiers, and fiber optic gyroscopes.

PM Optical Isolator (Single-Stage) 1064nm 0.3W FC/APC

Idealphotonics offers a broad range of fiber optic isolators within the wavelength range of 780-1310nm. These isolators can be coupled with any single-mode fiber equipment purchased from the company (such as lasers, SLDs, SOAs, and gain modules). In this configuration, the device is characterized by the isolator, with measurement reports showing the performance of the OI output. The equipment can be spliced to prevent additional loss and feedback at the FC/APC connector. For fiber optic isolators within the 1060-1310nm wavelength range, the devices feature compact (55x5.5x5.5mm) lightweight packaging with a maximum input power of 300-500mW. In the shorter range (780-1055nm), another material is used that absorbs less optical power, and the OI is provided in a larger (up to 118x37x35mm) and heavier metal package. High-power OIs use the same material to achieve input powers of up to 1W input power.

10：90 1x2 1064nm Polarization Maintaining Fiber Coupler FC/APC

These 2x2 polarization maintaining (PM) fiber couplers are designed for 460-2200 nm, with selectable coupling ratios of 50:50, 75:25, 90:10, or 99:1. The 2x2 coupler is bidirectional and can be used for separating and mixing signals (see 2x2 coupling example label). Polarization maintaining couplers are made using panda shaped polarization maintaining fibers, so they can maintain a high polarization extinction ratio (PER) when light is emitted along the slow axis of the fiber. As shown in the figure on the right, the stress rod is parallel to the fiber core and applies stress, generating birefringence in the fiber core to achieve polarization maintenance. Typical applications of polarization maintaining couplers include optical sensors, optical amplifiers, and fiber optic gyroscopes.

Mid-Infrared TDLAS N2O ppm-level Concentration Analysis System 4.56um

TDLAS (Tunable Diode Laser Absorption Spectroscopy) is a new gas detection method developed based on the combination of a diode laser and a long optical path absorption cell, utilizing the wavelength modulation of the laser through the characteristic absorption region of the measured gas. The semiconductor laser source used in TDLAS technology has a spectral width much smaller than the gas absorption line broadening, resulting in single-line absorption spectra, making TDLAS a high-resolution absorption spectroscopy technique. Nitrous oxide (N2O), also known as laughing gas, is an inorganic compound with the chemical formula N2O. It is a hazardous chemical, a colorless gas with a sweet odor, and acts as an oxidizing agent that can support combustion under certain conditions. However, it is stable at room temperature and has mild anesthetic effects, causing laughter in some cases. When nitrous oxide enters the bloodstream, it can lead to oxygen deprivation, and prolonged inhalation can result in high blood pressure, fainting, and even heart attacks. Long-term exposure to such gases can also cause anemia and damage to the central nervous system.
