Measurement Display
The ELM-BH-PD Measurement Display offers a clear and intuitive interface that consolidates all essential information in a single view. It shows real-time refractive data for the lens — sphere value (S), cylinder (C), axis (A), prism (P), progressive addition (ADD), and pupillary distance (RPD/LPD) — along with a central target indicating the optical center of the lens and a concentric circle system for precise prism readings. The display automatically identifies the lens type, distinguishes between right and left lenses, and allows switching between automatic and manual measurement modes. With quick-access buttons for printing, resetting values, and configuring preferences, the ELM-BH-PD display streamlines workflow and ensures reliable readings with every measurement.

Measurement of Various Lenses
This automatic lensometer can measure single vision lenses, bifocal (trifocal) lenses, progressive power lenses, and contact lenses.
UV/Blue Light Transmittance Measurement
The measurements performed by the ELM-BH-PD include UV and blue light transmittance, pupillary distance, pupillary height in spectacle frames, and other standard lens measurements. This model uses a 525 nm green light source, close to the international standard wavelength. With this equipment, you can also measure the transmittance of lenses that block blue light from digital devices such as smartphones and LCDs. Two types of display modes are available: UV Transmittance Measurement Mode and Blue Light Transmittance Measurement Mode.
The UV and BLUE data can be displayed in a single graph, allowing the professional to view both trends at a glance.
Measurement of PD and Pupillary Height of Eyeglass Frames
Adjusting the central area of the lens with the direction indicator icon allows you to measure the distance between the centers of the left and right lenses and the pupillary height of the eyeglass frame.
PD Sensor
An integrated PD sensor enables easy frame PD measurement.
Hartmann Wavefront Sensor Technology (HWFS)
The ELM-BH-PD utilizes cutting-edge Hartmann Wavefront Sensor (HWFS) technology to reduce errors by compensating for light loss, providing accurate results you can rely on.
Automatic Lens Detection Mode
The lensometer can measure double and triple lenses in normal lens mode and includes an automatic lens detection mode. This mode simplifies operation; the ELM-BH-PD automatically determines the lens type and instantly performs the appropriate measurement; no mode selection is required.
LCD Tilt Function
The sharp and well-lit screen can be tilted forward and backward to ensure comfort whether you are sitting or standing, preventing neck and back strain from leaning over the device.
7-inch LCD Touch Screen
The 7-inch TFT-LCD touch screen monitor (800 x 480) is used to perform all operations, allowing test selection with just a few taps on the screen. Once measurements are completed, the results are displayed on the touch screen, and UV and blue light data are presented in a graph for quick evaluation.
Multilingual Support
The system supports six languages: English, French, Portuguese, Chinese, Japanese, and Arabic.
Auto Cutting Printer
Data is stored for future review and can be printed with the integrated automatic cutting thermal printer.
Multiple Interfaces Available (RS-232, Wi-Fi)
The ELM-BH-PD features robust connectivity; users can share data between the lensometer and other Ezer digital ophthalmic instruments using the optional Wi-Fi connectivity module. By connecting the ELM-BH-PD to instruments such as the EDR-BH Auto Digital Refractor and the ERK-BH Auto Ref-Keratometer, clinics can leverage device synergy to save time and effort in data entry and testing.
DIGITAL CLINIC
With the ELM-BH-PD by Ezer, physicians and technicians obtain fast and accurate results with the utmost confidence, ensuring that patients receive the lenses they need.
What is an EMR? Electronic Medical Records, commonly abbreviated as “EMR,” are a technological tool widely used in modern medical practices. EMR systems were designed to replace outdated paper-based record-keeping methods and to streamline the collection and tracking of patient data over time. EMR platforms integrate the various components of a medical office visit, including intake demographic data and medical history, prescription information, laboratory data, practice management software, examination notes, and more. In general, EMR systems are used to promote economic efficiency and improve patient care through seamless coordination of data collection and storage. EMR platforms also increase patient transparency through the use of portals where patients can view important results and communicate with physicians securely.
In the ophthalmic industry, EMR systems are increasingly important and more popular than ever. The ability to store critical laboratory data related to prescriptions and diagnoses while maintaining quick access to that information is key to reducing chair time and improving patient outcomes and satisfaction. With Ezer Digital Practice, sharing information is easier than ever! The ELM-BH-PD Lensometer, the ERK-H/BH Autorefractor, the EDR-H Phoropter, and the EDC-BH Visual Acuity Chart interact via Wi-Fi to streamline communication between your pre-testing and examination rooms.
We know it can be intimidating to introduce new technology into your practice, but with Ezer Digital Practice equipment and the superior technical support of US Ophthalmic, your practice will save time and money with seamless EMR integration.
