Galaies Sun Filter
Product Overview
The Galaies Sun Filter is a precision-designed accessory that attaches to a surveying instrument’s objective lens to protect both the instrument’s optics and the operator’s eyes when working under bright sunlight or when conducting solar observations. Built with locally sourced materials and crafted for reliability in Indian field conditions, this accessory ensures safety, clarity, and extended equipment life especially critical during daylight operations and solar-based surveying tasks.
What is a Sun Filter and Why It’s Needed
- When surveying instruments (like theodolites or total stations) are used under strong sunlight for example, for solar observations or aligning with sun bearings direct sunlight entering through the telescope can damage internal optics or, worse, harm the user’s eyes.
- A sun (solar) filter placed on the objective lens attenuates (reduces) the sun’s brightness to safe levels, allowing the user to sight the sun (or bright reflective targets) without risking eye damage or instrument damage.
- For many surveying tasks particularly those involving determination of azimuths using the sun (sun-shots / solar observations) using a proper filter is mandatory according to instrument manuals.
Key Features & Benefits
- Safety for operator and instrument: The filter ensures that harmful solar radiation is blocked, preventing eye injury and protecting internal optics or EDM components from overheating or damage.
- Clear visibility under bright conditions: By reducing glare and controlling light intensity, the filter enables accurate observations and alignment even under direct sun useful for sun-based azimuth observations or bright-day surveying.
- Easy mounting & removal: Designed to fit standard surveying instrument objective lenses (theodolites, total stations, telescopes) attaching firmly yet removable for normal (non-solar) operations.
- Durable & weather-ready build: Made to resist dust, heat, and field rough handling suitable for Indian climates and construction site conditions.
- Local manufacturing & serviceability: As a Made-in-India product under Galaies, it offers easy availability, spare parts, affordable replacement, and quick support in local market ideal for surveyors working across Indian terrain and sites.
- Compatibility with solar observation workflows: Enables usage of “sun-shots” or solar-azimuth methods safely many traditional surveying and geodetic workflows rely on solar observation, where having a reliable solar filter is essential.
Applications
- Solar-based surveying / astronomical observations (azimuth determination by sun)
- Daylight site surveys under strong sunlight
- Construction layout and alignment when using telescope-based instruments during intense daylight
- Geodetic, boundary or cadastral surveys in open fields or rural areas
- Any scenario demanding safe, glare-free vision through optical surveying instruments
Why Choose Galaies Sun Filter
- Manufactured domestically ensuring dependable quality, lower cost, and easier replacement of parts.
- Designed to meet field-level requirements under Indian climatic and working conditions (dust, heat, rough terrain).
- Provides a safe, reliable way to extend the functionality of your surveying instruments to solar observations and bright-daywork without compromising optics or operator safety.
- A cost-effective accessory that adds significant versatility and safety to existing instruments (theodolite / total station / telescope) a small investment that enhances usability and lifespan.
