Overview

1. Function Description
2. Usage Features
3. Maintenance Features

The AmScope HL250-A Series is a line of halogen cold-light illuminators designed to provide bright, cool illumination for various microscopy applications. This user manual covers the HL250-A model and its packages, including HL250-AY, HL250-AR, and HL250-OYS, offering comprehensive guidance on assembly, operation, and maintenance. The illuminators are precision instruments, and proper handling is emphasized to ensure longevity and optimal performance.

Function Description

The primary function of the HL250-A Series illuminators is to provide a powerful and adjustable light source for microscopes, particularly stereo microscopes. These units utilize a halogen lamp to generate intense light, which is then directed to the sample via various attachments such as goosenecks or ring lights. The "cold-light" aspect refers to the design that minimizes heat transfer to the sample, preventing damage to sensitive specimens during prolonged observation.

The HL250-A model, as depicted, features a main unit with a lamp housing, a cooling fan, and controls for power and intensity. It includes a 2-step attachment point for connecting different light guides. The HL250-AY package incorporates a dual gooseneck attachment, allowing for flexible and precise illumination from two angles. The HL250-AS package comes with a single gooseneck attachment, offering a focused and maneuverable light source. The HL250-AR package is equipped with a ring light attachment, which mounts directly onto the microscope's objective, providing even, shadow-free illumination ideal for observing three-dimensional objects.

The illuminators are designed to enhance visibility and detail when working with microscopes, making them suitable for a wide range of tasks from industrial inspection to biological research. The ability to control light intensity and direction is crucial for optimizing image contrast and clarity, especially when examining samples with varying reflective properties or complex topographies.

Usage Features

The HL250-A Series illuminators are designed for straightforward assembly and operation. Upon unpacking, users are advised to ensure all parts are intact and to familiarize themselves with the components.

• Assembly: The illuminator attachment (single gooseneck, dual gooseneck, or ring light) connects to a 2-step connector on the main unit. For HL250-AR models, the ring light attaches to an adapter that screws onto the microscope's objective lens or any existing Barlow lenses.
• Power Connection: The unit connects to a power source via a standard power cable. It is crucial to verify that the power supply voltage matches the illuminator's voltage (e.g., 110V unit with a 110V source). For 220V power sources, a step-down transformer is required to prevent damage to the unit and bulb.
• Intensity Control: Each model features an "Intensity Knob" or "Intensity Control" that allows users to adjust the brightness of the light output. This feature is essential for fine-tuning illumination to suit different samples and observation requirements.
• Power Switch: A clear "Power Switch" (ON/OFF) is provided for easy control of the illuminator.
• Cooling System: The main unit includes a "Cooling Fan" to dissipate heat generated by the halogen bulb, ensuring stable operation and preventing overheating.
• Bulb Replacement: The manual provides detailed instructions for changing the bulb, which is a common maintenance task. Access to the bulb is gained by removing a top panel secured by a screw. The bulb itself is held by two metal pins and slides out after the socket is removed.
• Versatility: The different package options (HL250-AY, HL250-AS, HL250-AR) cater to various lighting needs. Gooseneck illuminators offer flexible spot lighting, while ring lights provide uniform, shadow-free illumination, particularly beneficial for stereo microscopes.
• Definition of Parts: The manual includes a comprehensive "Definition of Parts" section, explaining common microscope and illuminator terms such as "Adjustable Trinocular Port," "Boom Stand," "Coaxial Light," "Continuous Zoom," "Dimmer," "Diopter," "Fixed Power," "Focusing Knob," "Gooseneck Illuminator," "Head Lock Screw," "Magnification Knob," "Microscope Head," "Ocular Tube," "Ring Light," "Simul-Focal Microscope Head," and "Table Stand." This glossary helps users understand the terminology associated with their microscopy setup.

Maintenance Features

Proper maintenance is crucial for preserving the performance and longevity of the AmScope HL250-A Series illuminators. The manual outlines several key precautions and cleaning procedures:

• Handling: The illuminator is a precision instrument and should always be handled with care. Users are advised to avoid impact or abrupt movements during transportation and to refrain from shaking the package.
• Environmental Conditions: The device should be kept indoors in a dry and clean place, away from direct sunlight and high heat. The recommended operating temperature range is 32-100 degrees F (0-40 degrees C), with a maximum relative humidity of 85%.
• Lens Care:
  • All glass surfaces must be kept clean. Fine dust should be removed using a hand blower or by gently wiping with a soft, non-abrasive lint-free cloth or lens paper.
  • Oil or fingerprints on lens surfaces should be carefully wiped off with tissue moistened with a small amount of lens cleaner (Sparkle brand optical cleaner is recommended).
  • It is important not to use Sparkle cleaner on other microscope elements. A neutral detergent should be used for cleaning plastic or painted surfaces.
• Electrical Components: Users are strongly advised against assembling or disassembling the microscope's electrical components without advisement from an AmScope technician. Unauthorized tampering will void the warranty.
• Storage: After use, the microscope should be covered with the provided dust cover. It should be stored in a dry, clean location to prevent rust or other forms of damage.
• Bulb Replacement Safety: When changing the bulb, it is imperative to ensure the unit is turned off and allowed to cool completely to prevent burns or damage.

By adhering to these usage and maintenance guidelines, users can ensure their AmScope HL250-A Series illuminator provides reliable and high-quality performance for many years.
