Grand Seiko GL-7000 Auto Lensmeter Product Analysis Report

Device Identification

The device in the visual is an automatic lensmeter (Auto Lensmeter) used in the optical sector to measure the diopter (power), axis, and cylindrical values of spectacle lenses. The device has a compact, all-in-one design suitable for desktop use.

Brand and Model

On the side body of the device, the large logo and the model designation immediately below it clearly indicate the brand as Grand Seiko Co., Ltd. and the model as GL-7000 AUTO LENSMETER. Additionally, the model name “GL-7000” is confirmed on the label located at the rear of the device. The manufacturer is stated as Seiko PENTAX CO., LTD. on the label.

Originality

The print quality of the brand logo on the product, the detailed content of the technical information label (serial number, voltage values, manufacturer information, and origin), industrial design features, and the “Made in Japan” inscription indicate that the device is an original Japanese-made optical instrument.

Areas of Use

This device is used in professional optical stores and eye health clinics. It is designed for determining the optical center of spectacle lenses, measuring lens powers (SPH, CYL, AXIS), and analyzing technical data such as UV transmittance. The device is for professional use only.

Quantity Information

The visual shows a total of 1 unit of the Grand Seiko GL-7000 Auto Lensmeter main unit. No spare parts or external units (e.g., printer paper, calibration eye, etc.) are present in the visual.

General Condition

Visually, the device is in second-hand condition, and it is clearly understood that it has been used. The white plastic casing of the device shows dirt accumulation over time and signs of use. However, its structural integrity appears to be intact.

Physical Deformation

Upon detailed examination of the product’s outer casing, the following points are noteworthy:

• The curved white plastic part on the upper body of the device has noticeable black and gray scuff marks/stains.
• Scattered dust and dirt marks are visible on the side panels, in the areas where the brand logo is located, and on the lower base sections.
• No visible large cracks or breaks have been detected in the plastic casing, but it appears to require extensive cosmetic cleaning.

Mechanical Components

The body containing the display screen is mounted to the main casing from the right side. The lens placement tray for measurement and the 3-pronged lens marking pin mechanism on it are present in the visual. Parts such as the lens clamping lever or nose piece are located in the measurement area.

Electronic Components

On the right side of the device in the visual, an RS-232C data transfer port, a fuse slot, and the “POWER” on/off switch are clearly visible. Since the device is not connected to electricity, it was not possible to analyze whether the screen is working or if its electronic functions are active.

Screen Analysis

Integrated into the right side of the device is a square-shaped screen, likely utilizing CRT or an older type of LCD technology. The screen is currently off. The area containing the keypad/inputs on the control panel below the screen is framed by the section where the device’s model name (GL-7000) is written.

Label Information

The silver-colored technical label on the left side panel of the device contains the following information:

• Product Type: AUTO LENSMETER
• Model: GL-7000
• Voltage: AC 100-120V / 220-240V (Globally compatible power input)
• Frequency: 50/60 Hz
• Power Consumption: 50VA
• Manufacturer: Seiko PENTAX CO., LTD.
• Origin: MADE IN JAPAN
• Other Codes: In the Serial No. field, a number starting with “80…” is present, but due to the angle and resolution in the visual, the entire number cannot be read with 100% certainty.
• Distributor: Distributor information starting with Luneau is also visible on the label.

Accessories and Sockets

The power cable required for the device to operate is not present in the visual; the power input socket is empty. The RS-232C socket used for data transfer is empty. There is no external dust cover or calibration accessory in the device’s measurement tray.

Existing Faults and Risks

There is no “Out of Order” or similar fault label on the device. However, the black scuff marks on the upper part of the casing suggest that the device may have been handled carelessly during transport or storage. Since the power cable is not connected, the condition of the electronic boards or the screen is uncertain. Apart from the cosmetic imperfections on the outer casing, no physical break (that would compromise mechanical integrity) is visible.

Dimensions and Compatibility

The device is sized to be placed on a standard desk or workbench. Its design is suitable for measuring adult and child spectacle frames. It has universal compatibility for all standard spectacle lenses (monofocal, bifocal, progressive) and contact lenses (with a special adapter).
