Like new. It was opened and put on a shelf until now. Guaranteed to work like new. Here is the Thorlabs description: Features Thin Profile [3/4" (19.1 mm)] Allows Measurements in Tight Spaces SM05 Lens Tube, SM1 Lens Tube, Cage System, and ?1/2" Post Compatible Internal A23 Bias Battery Can be Fiber Coupled Using Our Fiber Adapters Thorlabs' biased photodetectors are available in ten models that cover the wavelength range from the UV to the mid-IR (150 nm to 2.6 µm) with improved bandwidth and NEP performance over previous models. The slim housing allows the optical detector to slip into tight setups. Each model comes complete with a fast PIN photodiode and an internal bias battery packaged in a rugged aluminum housing. Thorlabs also offers high-speed free-space detectors and high-speed fiber-coupled detectors for wavelengths between 400 - 1700 nm. Our biased photodetectors are compatible with our benchtop photodiode amplifier. With a wide bandwidth DC-coupled output, these detectors are ideal for monitoring fast pulsed lasers as well as DC optical sources. The direct photodiode anode current is provided on a side panel BNC. This output is easily converted to a positive voltage using a terminating resistor. When looking at high-speed signals, Thorlabs recommends using a 50 ? load resistor. For lower bandwidth applications, our variable terminator or fixed stub-style terminators quickly adjusts the measured voltage. All connections and controls are located away from the light path, which simplifies integration of our detectors in enclosed spaces. The SM1 (1.035"-40), SM05 (0.535"-40), and 8-32 (M4 for items ending in /M) threadings on the DET detector housing allow it to be mounted in a cage system, lens tube system, or on a ?1/2" optical post. See the Mounting Options tab for more details on how to incorporate a DET series photodetector into an optical setup.Each detector is reverse-biased by an A23 12 VDC battery incorporated into the housing. The housing also includes a red button (pictured to the left) which, when held down, applies the battery's voltage across the external load. For a high Z load, this will output the battery's voltage over BNC, providing an easy way to determine if the battery should be replaced without removing it from the housing. An in-line current-limiting resistor (1.05 k?) prevents fast battery drainage if the battery is tested while connected to a 50 ? load. Please note that due to slight physical variations of the positive terminal from manufacturer to manufacturer, Thorlabs only recommends using an Energizer battery in our DET series of photodetectors. A battery was chosen for the reverse bias because it provides an extremely low noise source of power. If the finite lifetime of a battery is not acceptable, the battery can be replaced by a DET1B Power Supply Kit. Please note that inhomogeneities at the edges of the active area of the detector can generate unwanted capacitance and resistance effects that distort the time-domain response of the photodiode output. Thorlabs therefore recommends that the incident light on the photodiode is well centered on the active area. The SM1 (1.035"-40) threading on the housing is ideally suited for mounting a ?1" focusing lens or pinhole in front of the detector element.
