GERMANIUM(Ge) WAFERS are semiconductor materials made from Germanium, a group IV element with properties that make it useful in various electronic applications. Historically, Germanium was one of the first materials used in transistors and is still utilized in some specialized applications today, particularly in high-speed electronics and photonics due to its favorable electronic and optical properties.
We offer the following Germanium Wafers:
Undoped Germanium Wafers: Pure Germanium with no intentional doping. These wafers are often used in experimental and research settings to investigate intrinsic semiconductor properties.
N-type Germanium Wafers: Doped with donor impurities (such as phosphorus or arsenic) to increase the concentration of electrons. These wafers are commonly used in transistor applications and other electronic circuits.
P-type Germanium Wafers: Doped with acceptor impurities (such as boron or gallium) to create electronic holes. P-type wafers are often used in diode and transistor applications.
High Purity Germanium Wafers: Extremely low levels of impurities, often used in specialized applications such as radiation detectors and other high-performance devices.
Germanium-on-Insulator (GOI) Wafers: A structure where a thin layer of germanium is bonded to an insulating substrate. This is used to improve device performance and reduce parasitic capacitance.
Thin-Film Germanium Wafers: Thin layers of Germanium material that are used in advanced applications such as flexible electronics and integrated circuits.

NFXI-OPT
The Opal photoelectric smoke detector has a completely new detection chamber design, the result of many years of research and development. This delivers improved responsiveness, reduced sensitivity changes caused by settling dust and reduced false alarms resulting from ingress of insect and other debris. The plug-in unit uses sophisticated processing circuitry that incorporates smoothing filters to help eliminate transient environmental noise conditions that can be the cause of unwanted alarms. The devices are managed by embedded software running complex algorithms that further improve resilience to false alarms and improve detection speed.

The Conventional Reflective Beam Detector has built in Laser beam pointing and Digital guide display for real
user friendly alignment method. The Laser beam pointing accurately point the exact location where to mount
mirror and with additional digital guide display allows to monitor and guide on the actual light intensity between
the mirror and detector which cannot be seen by our naked eye making it more easy and convenient in
alignment commissioning.
The beam detector has four adjustable operational range of between 8 to 20, 40, 70 and 100 meters beside
with three adjustable sensitivity setting ranges from 2.6dB to 4.8dB to meet the specific environmental
requirement. The detector works on the principle of reflective infrared beam obscuration. Used in conjunction
with a reflectors, it will notify the fire alarm panel when the infrared beam is obscured by smoke. Secure and
quick communication through the onboard processor enables the detector to make its own decision and drift
compensation resulting in greater automation.
The detector is ideal for use high ceiling and wide areas such as warehouses, large storages, shopping malls,
leisure centres, exhibition halls, hotel lobbies, printing houses, garment factories, museums and prisons, as well
as places where slight smoke particles or corrosive gas exist.
Feature and Benefits
1. Manufacture in compliance with EN54-12
2. Hassle free alignment, built with digital guide display and laser beam pointing
3. Employ single-ended design through reflective mirror.
4. Four ranges wide monitoring from 8-100 meters via encoder
5. Three users programing sensitivity adjustment
6. Built-in microprocessor
7. Self-diagnosis function can monitor for internal faults
8. Automatic compensation for factors weakening received signals, such as dust contamination, positional
movement and ageing of the transmitter
9. Fire and Fault interfacing relays
10. Attractive and pleasing appearance
11. Real User friendly alignment method
Our most advanced intelligent spot detectors, multi-criteria/multi-sensor devices use multiple sensors to detect various conditions in an environment sensing a wider range of fires with greater accuracy.
Features & Benefits:
